    Old (>100 years, situated below 15 cm depth) sediment layers, of two humic forest lakes contained 400 to 600 mg of solvent soluble organic halogen (EOX) (kg C)-1. This was two to three fold more than in the most recent layers at the depth of 0 to 10 cm. Sediment accumulation of EOX in humic forest lakes correlated positively with the sediment accumulation of organic matter. Lake water concentration of adsorbable organic halogen (AOX) correlated positively with water concentration of total organic carbon (TOC) and with the water colour in the different strata, seasons and lakes. These facts suggest that organic halogen in boreal humic lakes originated from the drainage area. Paleolimnological study of diatom remains showed that sediment concentration of organic halogen correlated negatively with the historical pH of the lake water column. This fact supports a view that the presence of organic halogen was promoted by haloperoxidase type of enzyme, which is most active at low pH (3.5 to 4). The dates of forest management events (clear cutting, prescribed burning) matched with the observed changes in lake water column historical pH and decrease in sediment content organic halogen in dated sediment layers. Clear cutting and prescribed burning are known to increase soil pH. This may decrease the intrinsic formation of organic halogens in soil, thereby decreasing the flow of organic halogens from the runoff area to the forest lake. Our results support a conclusion that changes in natural organically bound halogen in the sediment were promoted by acidification, forest fires and forest management in the drainage area. The organic halogen content in the most polluted layer of the pulp mill recipient sediment was 10 to 100 fold as compared to forest lake sediments.

    Abstract. We present the results of pollen analyses from a 1105-cm-long sediment core from Wuxu Lake in southwestern China, which depict the variations of the East Asian winter monsoon (EAWM) and the Indian summer monsoon (ISM) during the last 12.3 ka. During the period of 12.3 to 11.3 cal ka BP, the dominance of Betula forest and open alpine shrub and meadow around Wuxu Lake indicates a climate with relatively cold winters and dry summers, corresponding to the Younger Dryas event. Between 11.3 and 10.4 cal ka BP, further expansion of Betula forest and the retreat of alpine shrubs and meadows reflect a greater seasonality with cold winters and gradually increasing summer precipitation. From 10.4 to 4.9 cal ka BP, the dense forest understory, together with the gradual decrease in Betula forest and increase in Tsuga forest, suggest that the winters became warmer and summer precipitation was at a maximum, corresponding to the Holocene climatic optimum. Between 4.9 and 2.6 cal ka BP, Tsuga forest and alpine shrubs and meadows expanded significantly, reflecting relatively warm winters and decreased summer precipitation. Since 2.6 cal ka BP, reforestation around Wuxu Lake indicates a renewed strengthening of the ISM in the late Holocene; however, the vegetation in the catchment may also have been affected by grazing activity during this period. The results of our study are generally consistent with previous findings; however, the timing and duration of the Holocene climatic optimum from different records are inconsistent, reflecting real contrast in local rainfall response to the ISM. Overall, the EAWM is broadly in-phase with the ISM on the orbital timescale, and both monsoons exhibit a trend of decreasing strength from the early to late Holocene, reflecting the interplay of solar insolation receipt between the winter and summer seasons and El Niño Southern Oscillation strength in the tropical Pacific.

    Abstract More than one hundred and thirty coal seams and coaly layers occur in the Donets Basin (Donbas). Twenty-eight (52 samples) of them, ranging in age from Serpukhovian (Late Mississipian) to Gzhelian (Late Pennsylvanian), 33 clastics and three limestones were studied in terms of maceral composition, sulphur contents, and biomarker distribution. Diterpanes are used to estimate the contribution of different groups of plants and the height of the water table in the swamp; hopanes are a measure of bacterial activity in the peat; and steranes indicate the relative input of wood and algae. Stratigraphic trends in these parameters are discussed in relation to paleoenvironment, climatic changes, and eustacy. A tropical climate prevailed in the Donbas from Serpukhovian to Kasimovian times. Nevertheless, periods with drier and wetter conditions can be distinguished based on maceral and biomarker data. Relatively dry conditions are observed during Serpukhovian and Vereian times, whereas wetter climates with a maximum of coal deposition occurred during the (late) Bashkirian, most of the Moscovian, and the earliest Kasimovian. No economic coal seams are hosted in upper Kasimovian and Gzhelian deposits, a result of a change to an arid climate. Our data also suggest climatic changes during sequences of different order. For the second-order, third-order, and fourth-order sequences, relatively dry or wet conditions occurred during coal deposition in the lowstand systems tract, an intermediate climate during the transgressive systems tract and the maximum flooding, and a wet climate during the highstand systems tract. The results for high frequency sequences support the Cecil's paleoclimatic model: an intermediate paleoclimate during LST (sandstone and levee siltstone), a wet climate during early TST (coal), and a dry climate during late TST (limestone), MFS (claystone), and HST (deltaic siltstone). Coals deposited during maximum flooding periods are more enriched in C27 steranes derived from algae, and contain lower proportions of C29 steranes derived from the wood of higher plants.

    International audience; The purpose of this study is to characterize factors controlling the nature and distribution of the diagenetic phases that gave rise to carbonate reservoirs. To do so, a pluridisciplinary approach was carried out, integrating sedimentologic and diagenetic studies on the Madison Formation (Lower Carboniferous, 357-340 My) which is a carbonate reservoir in subsurface.The Madison Formation, outcropping in the Bighorn Basin (Wyoming, USA), is a 340 m thick carbonate series composed of four to seven 3rd-order depositional sequences (S1 to S7) depending of the palaeogeographic location. The first three sequences (S1 to S3) were deposited under arid and warm conditions during Tournaisian times which favoured high accumulation of carbonates leading to a morphological change from a quite flat ramp (S1 to S2) to a wide platform (S3). It also probably favoured the early calcite cementation (isopachous and syntaxial calcite cements) of the subtidal deposits and the early dolomitization (D1) of the supratidal to intertidal sabkha ones. In addition, the very flat profile occurring during S3 was also responsible for the postponed dolomitization (D2) of S1-S2 due to reflux of brines, at various degrees depending on the palaeogeographic location. The deposition of S4 to S7 under humid conditions during Visean times were associated with 1) a decrease of the carbonate accumulation and of the dolomitization; 2) dissolution processes at micro- (pores network) and macro-scales (karst, collapse breccia...) and calcite cementation (C1). The spatial distribution of all these first diagenetic phases acts as a controlling factor on the distribution of the later burial diagenetic phases. Thus, the mesogenetic calcite cements are mostly observed in the secondary porosity created by dissolution (karsts, collapse breccias) or dolomitization. The burial diagenesis of the Madison Formation were characterized by 1) a dolomitization phase (D3) in proximal parts of the platform leading to an increase of porosity and permeability and 2) calcite cementations (C2-C3) in the distal parts of the platform leading to a decrease of these properties.The Madison Formation provides a good spatial representation of sedimentary and diagenetic heterogeneities that may occur in the carbonate reservoirs due to various palaeogeographic locations, climates, burial history and structures.

    Traditional settlement pattern analysis involves classifying sites within a region using previously established functional categories. Faunal and lithic data are frequently combined as archaeological indicators of site function. The results are interpreted in terms of a settlement system from which inferences about mobility patterns and social organization are drawn. The previously published site of Karabi Tamchin is used here as a spring-point for a discussion of the problems inherent with established site typologies and some of the settlement models that have been proposed in the past. The rich Middle Paleolithic archaeological record of Crimea is used to demonstrate the usefulness of the landscape approach as a means of supplementing existing information about Middle Paleolithic settlement patterns.

    The paper investigates the superficial layers of an archaeological landscape based on the integration of various remote sensing techniques. It is well known in the literature that shallow depths may be rich in archeological remains, which generate different signal responses depending on the applied technique. In this study three main technologies are examined, namely ground-penetrating radar (GPR), ground spectroscopy, and multispectral satellite imagery. The study aims to propose a methodology to enhance optical remote sensing satellite images, intended for archaeological research, based on the integration of ground based and satellite datasets. For this task, a regression model between the ground spectroradiometer and GPR is established which is then projected to a high resolution sub-meter optical image. The overall methodology consists of nine steps. Beyond the acquirement of the in-situ measurements and their calibration (Steps 1–3), various regression models are examined for more than 70 different vegetation indices (Steps 4–5). The specific data analysis indicated that the red-edge position (REP) hyperspectral index was the most appropriate for developing a local fusion model between ground spectroscopy data and GPR datasets (Step 6), providing comparable results with the in situ GPR measurements (Step 7). Other vegetation indices, such as the normalized difference vegetation index (NDVI), have also been examined, providing significant correlation between the two datasets (R = 0.50). The model is then projected to a high-resolution image over the area of interest (Step 8). The proposed methodology was evaluated with a series of field data collected from the Vésztő-Mágor Tell in the eastern part of Hungary. The results were compared with in situ magnetic gradiometry measurements, indicating common interpretation results. The results were also compatible with the preliminary archaeological investigations of the area (Step 9). The overall outcomes document that fusion models between various types of remote sensing datasets frequently used to support archaeological research can further expand the current capabilities and applications for the detection of buried archaeological remains.

    Abstract Species distribution modeling (SDM) is a methodology that has been widely used in the past two decades for developing quantitative, empirical, predictive models of species–environment relationships. SDM methods could be more broadly applied than they currently are to address research questions in archaeology and paleoanthropology. Specifically, SDM can be used to hindcast paleodistributions of species and ecological communities (paleo-SDM) for time periods and locations of prehistoric human occupation. Paleo-SDM may be a powerful tool for understanding human prehistory if used to hindcast the distributions of plants, animals and ecological communities that were key resources for prehistoric humans and to use this information to reconstruct the resource landscapes (paleoscapes) of prehistoric people. Components of the resource paleoscape include species (game animals, food plants), habitats, and geologic features and landforms associated with stone materials for tools, pigments, and so forth. We first review recent advances in SDM as it has been used to hindcast paleodistributions of plants and animals in the field of paleobiology. We then compare the paleo-SDM approach to paleoenvironmental reconstructions modeled from zooarchaeological and archaeobotanical records, widely used in archaeology and paleoanthropology. Next, we describe the less well developed but promising approach of using paleo-SDM methods to reconstruct resource paleoscapes. We argue that paleo-SDM offers an explicitly deductive strategy that generates spatial predictions grounded in strong theoretical understandings of the relation between species, habitat distributions and environment. Because of their limited sampling of space and time, archaeobiological records may be better suited for paleo-SDM validation than directly for paleoenvironmental reconstruction. We conclude by discussing the data requirements, limitations and potential for using predictive modeling to reconstruct resource paleoscapes. There is a need for improved paleoclimate models, improved paleoclimate proxy and species paleodistribution data for model validation, attention to scale issues, and rigorous modeling methods including mechanistic models.

    Palaeoecological methods can provide an environmental context for archaeological sites, enabling the nature of past human activity to be explored from an indirect but alternative perspective. Through a palynological study of a small fen peatland located within the catchment of a multi-period prehistoric complex at Ballynahatty, Co. Down, Northern Ireland, we reconstruct the vegetation history of the area during the early prehistoric period. The pollen record reveals tentative evidence for Mesolithic activity in the area at 6410–6220 cal BC, with woodland disturbance identified during the Mesolithic–Neolithic transitional period ca. 4430–3890 cal BC. A more significant impact on the landscape is observed in the Early Neolithic from 3950 to 3700 cal BC, with an opening up of the forest and the establishment of a mixed agricultural economy. This activity precedes and continues to be evident through the Mid-Neolithic during which megalithic tombs and related burial sites were constructed at Ballynahatty. Due to chronological uncertainties and a possible hiatus in peat accumulation in the fen, the contemporary environment of the Ballynahatty timber circle complex (constructed and used ca. 3080–2490 cal BC) and henge (dating to the third millennium cal BC) cannot certainly be established. Nevertheless, the pollen record suggests that the landscape remained open through to the Bronze Age, implying a long continuity of human activity in the area. These findings support the idea that the Ballynahatty prehistoric complex was the product of a gradual and repeated restructuring of the ritual and ceremonial landscape whose significance continued to be recognised throughout the early prehistoric period.

    Sustainable resource management is of central importance among agrarian societies in marginal drylands. In the Negev Desert, Israel, research on agropastoral resource management during Late Antiquity emphasizes intramural settlement contexts and landscape features. The importance of hinterland trash deposits as diachronic archives of resource use and disposal has been overlooked until recently. Without these data, assessments of community-scale responses to societal, economic, and environmental disruption and reconfiguration remain incomplete. In this study, micro-geoarchaeological investigations were conducted on trash mound features at the Byzantine—Early Islamic sites of Shivta, Elusa, and Nesanna to track spatiotemporal trends in the use and disposal of critical agropastoral resources. Refuse derived sediment deposits were characterized using stratigraphy, micro-remains (i.e., livestock dung spherulites, wood ash pseudomorphs, and plant phytoliths), and mineralogy by Fourier transform infrared spectroscopy. Our investigations detected a turning point in the management of herbivore livestock dung, a vital resource in the Negev. We propose that the scarcity of raw dung proxies in the studied deposits relates to the use of this resource as fuel and agricultural fertilizer. Refuse deposits contained dung ash, indicating the widespread use of dung as a sustainable fuel. Sharply contrasting this, raw dung was dumped and incinerated outside the village of Nessana. We discuss how this local shift in dung management corresponds with a growing emphasis on sedentised herding spurred by newly pressed taxation and declining market-oriented agriculture. Our work is among the first to deal with the role of waste management and its significance to economic strategies and urban development during the late Roman Imperial Period and Late Antiquity. The findings contribute to highlighting top-down societal and economic pressures, rather than environmental degradation, as key factors involved in the ruralisation of the Negev agricultural heartland toward the close of Late Antiquity.

    Located between modern-day South Africa and Tanzania, both of which have well-known and extensive Stone Age records, Mozambique's Stone Age sequence remains largely unknown in the broader context of African Pleistocene prehistory. Such lack of data occurs despite the key geographical location of the country, in southern Africa at the southeastern tip of the Great Rift Valley. As such, Mozambique is an area of interest to evaluate the origins and dispersion of Homo sapiens within Africa, particularly in relation to Middle Stone Age contexts and associated early modern human ecology and cognition.This paper focuses on preliminary survey results from the Niassa District, near Lake Niassa (also known as Lake Malawi) in northern Mozambique. The results include the discovery and location of more than 80 new surface lithic concentration localities, as well as data from two new sites, the open air surface site of Ncuala and the rock shelter of Chicaza. For Chicaza we provide a series of new radiocarbon dates for the Iron Age and Late Stone Age occupations based on preliminary testing carried out at the site. (C) 2015 Elsevier Ltd and INQUA.

    Old (>100 years, situated below 15 cm depth) sediment layers, of two humic forest lakes contained 400 to 600 mg of solvent soluble organic halogen (EOX) (kg C)-1. This was two to three fold more than in the most recent layers at the depth of 0 to 10 cm. Sediment accumulation of EOX in humic forest lakes correlated positively with the sediment accumulation of organic matter. Lake water concentration of adsorbable organic halogen (AOX) correlated positively with water concentration of total organic carbon (TOC) and with the water colour in the different strata, seasons and lakes. These facts suggest that organic halogen in boreal humic lakes originated from the drainage area. Paleolimnological study of diatom remains showed that sediment concentration of organic halogen correlated negatively with the historical pH of the lake water column. This fact supports a view that the presence of organic halogen was promoted by haloperoxidase type of enzyme, which is most active at low pH (3.5 to 4). The dates of forest management events (clear cutting, prescribed burning) matched with the observed changes in lake water column historical pH and decrease in sediment content organic halogen in dated sediment layers. Clear cutting and prescribed burning are known to increase soil pH. This may decrease the intrinsic formation of organic halogens in soil, thereby decreasing the flow of organic halogens from the runoff area to the forest lake. Our results support a conclusion that changes in natural organically bound halogen in the sediment were promoted by acidification, forest fires and forest management in the drainage area. The organic halogen content in the most polluted layer of the pulp mill recipient sediment was 10 to 100 fold as compared to forest lake sediments.

    Abstract. We present the results of pollen analyses from a 1105-cm-long sediment core from Wuxu Lake in southwestern China, which depict the variations of the East Asian winter monsoon (EAWM) and the Indian summer monsoon (ISM) during the last 12.3 ka. During the period of 12.3 to 11.3 cal ka BP, the dominance of Betula forest and open alpine shrub and meadow around Wuxu Lake indicates a climate with relatively cold winters and dry summers, corresponding to the Younger Dryas event. Between 11.3 and 10.4 cal ka BP, further expansion of Betula forest and the retreat of alpine shrubs and meadows reflect a greater seasonality with cold winters and gradually increasing summer precipitation. From 10.4 to 4.9 cal ka BP, the dense forest understory, together with the gradual decrease in Betula forest and increase in Tsuga forest, suggest that the winters became warmer and summer precipitation was at a maximum, corresponding to the Holocene climatic optimum. Between 4.9 and 2.6 cal ka BP, Tsuga forest and alpine shrubs and meadows expanded significantly, reflecting relatively warm winters and decreased summer precipitation. Since 2.6 cal ka BP, reforestation around Wuxu Lake indicates a renewed strengthening of the ISM in the late Holocene; however, the vegetation in the catchment may also have been affected by grazing activity during this period. The results of our study are generally consistent with previous findings; however, the timing and duration of the Holocene climatic optimum from different records are inconsistent, reflecting real contrast in local rainfall response to the ISM. Overall, the EAWM is broadly in-phase with the ISM on the orbital timescale, and both monsoons exhibit a trend of decreasing strength from the early to late Holocene, reflecting the interplay of solar insolation receipt between the winter and summer seasons and El Niño Southern Oscillation strength in the tropical Pacific.

    Abstract More than one hundred and thirty coal seams and coaly layers occur in the Donets Basin (Donbas). Twenty-eight (52 samples) of them, ranging in age from Serpukhovian (Late Mississipian) to Gzhelian (Late Pennsylvanian), 33 clastics and three limestones were studied in terms of maceral composition, sulphur contents, and biomarker distribution. Diterpanes are used to estimate the contribution of different groups of plants and the height of the water table in the swamp; hopanes are a measure of bacterial activity in the peat; and steranes indicate the relative input of wood and algae. Stratigraphic trends in these parameters are discussed in relation to paleoenvironment, climatic changes, and eustacy. A tropical climate prevailed in the Donbas from Serpukhovian to Kasimovian times. Nevertheless, periods with drier and wetter conditions can be distinguished based on maceral and biomarker data. Relatively dry conditions are observed during Serpukhovian and Vereian times, whereas wetter climates with a maximum of coal deposition occurred during the (late) Bashkirian, most of the Moscovian, and the earliest Kasimovian. No economic coal seams are hosted in upper Kasimovian and Gzhelian deposits, a result of a change to an arid climate. Our data also suggest climatic changes during sequences of different order. For the second-order, third-order, and fourth-order sequences, relatively dry or wet conditions occurred during coal deposition in the lowstand systems tract, an intermediate climate during the transgressive systems tract and the maximum flooding, and a wet climate during the highstand systems tract. The results for high frequency sequences support the Cecil's paleoclimatic model: an intermediate paleoclimate during LST (sandstone and levee siltstone), a wet climate during early TST (coal), and a dry climate during late TST (limestone), MFS (claystone), and HST (deltaic siltstone). Coals deposited during maximum flooding periods are more enriched in C27 steranes derived from algae, and contain lower proportions of C29 steranes derived from the wood of higher plants.
