L'IDA est calculé à partir de la standardisation du changement relatif des polluants introduits dans le modèle. La standardisation permet d'obtenir un score (z), calculé comme le score de changement brut (Δx) moins la moyenne arithmétique des rasters (m), divisé par l'écart-type des rasters (s) et multiplié par un facteur d'étirement défini (d). De cette manière, l'IDA peut être défini comme la somme des différences de rasters standardisées.

Abstract: The prevalence of antecrysts in arc volcanic rocks is widely accepted, yet the origin of their carrier melts remains debated. Crystal cargo in lava flows from Taranaki volcano, New Zealand, is dominated by plagioclase, clinopyroxene, and amphibole. Except for some crystal rims, mineral phases are in disequilibrium with the melt they are entrained in. Major element chemistry reveals an almost complete compositional overlap between the crystals in the lava and those in xenoliths. The large volume fraction of crystals (35–55 vol%) exerts a strong control on whole-rock compositions, reducing silica by 5–11 wt% compared to the carrier melt. Yet there is no clear relationship between mineral proportion and bulk rock compositions. Our data are inconsistent with extensive fractional crystallization, commonly invoked as a driver of magma evolution towards silica-rich compositions. Instead, high-temperature, aphyric carrier melts with varied compositions (55–68 SiO2 wt%) entrain crystal cargo while ascending through colder, low-silica rocks. Thus, some primary melts at Taranaki volcano are significantly more silica-rich than arc basalts commonly invoked as parental magmas. Further, thermometric and hygrometric constraints preclude a deep crustal hot zone for the source of these melts, which we argue are of subcrustal origin.

Abstract: The Central Asian Orogenic Belt (CAOB) represents a Late Paleozoic archipelago. Yet the crustal growth, reworking and exhumation of individual microcontinental massifs remain poorly constrained. Here, we utilize the Axi epithermal deposit to examine continental preservation and exhumation of CAOB in the Chinese Western Tianshan. Zircon U-Pb dating and geochemistry demonstrate that the andesitic host rock formed by incremental addition of magma in an Andean-type magmatic arc setting at 362, 354 and 342 Ma. Pyrite Re-Os data and textural evidence reveal two mineralization events at 355 and 332 Ma. Zircon (U-Th) /He data reveal temperatures of c. 180 °C until 317.8 ± 9.8 Ma, which is interpreted to record the timing of exhumation of the andesite and gold orebodies prior to their burial by Carboniferous aged sediments. Further sedimentary concealment continued until the Late Mesozoic, when the system was re-exhumed between 148.6 ± 8.6 and 120.0 ± 13 Ma at a rate of c. 9.8 m/Ma as shown by apatite (U-Th) /He data . Collectively, the geo-/thermochronology demonstrates that the Chinese Western Tianshan records the transition from compressional to extensional tectonism during the Late Paleozoic and the Late Mesozoic. The shallow epithermal mineralization was protected from erosion by post-mineralization deposition.

The metamorphic conditions of the Natal Metamorphic Province (NMP) have been the focus of previous studies to assist with Rodinia reconstructions but there are limited constraints on the age of metamorphism. We use a combination of modern techniques to provide new constraints on the conditions and timing of metamorphism in the two southernmost terranes; the Mzumbe and Margate. Metamorphism reached granulite facies, 780–834 °C at 3.9–7.8 kbar in the Mzumbe Terrane and 850–892 °C at 5.7–6.1 kbar in the Margate Terrane. The new P and T constraints are supportive of isobaric cooling in the Margate Terrane as previously proposed. Peak metamorphism of the two terranes is shown to have occurred ~40 million years apart, which contrasts strongly with previous assumptions of coeval metamorphism. While the age of peak metamorphism of the Margate Terrane (1032.7 ± 4.7 Ma) coincides with the tectonism and magmatism associated with the emplacement of the Oribi Gorge Suite (ca. 1050–1030 Ma), the age of metamorphism of the Mzumbe Terrane (987.4 ± 8.1 Ma) occurs ca. 30–40 Myrs after tectonism is previously thought to have finished. We propose that models of advective cooling during transcurrent shearing can explain the metamorphic conditions and timing of the NMP.

L'IDA est calculé à partir de la standardisation du changement relatif des polluants introduits dans le modèle. La standardisation permet d'obtenir un score (z), calculé comme le score de changement brut (Δx) moins la moyenne arithmétique des rasters (m), divisé par l'écart-type des rasters (s) et multiplié par un facteur d'étirement défini (d). De cette manière, l'IDA peut être défini comme la somme des différences de rasters standardisées.

Abstract: The prevalence of antecrysts in arc volcanic rocks is widely accepted, yet the origin of their carrier melts remains debated. Crystal cargo in lava flows from Taranaki volcano, New Zealand, is dominated by plagioclase, clinopyroxene, and amphibole. Except for some crystal rims, mineral phases are in disequilibrium with the melt they are entrained in. Major element chemistry reveals an almost complete compositional overlap between the crystals in the lava and those in xenoliths. The large volume fraction of crystals (35–55 vol%) exerts a strong control on whole-rock compositions, reducing silica by 5–11 wt% compared to the carrier melt. Yet there is no clear relationship between mineral proportion and bulk rock compositions. Our data are inconsistent with extensive fractional crystallization, commonly invoked as a driver of magma evolution towards silica-rich compositions. Instead, high-temperature, aphyric carrier melts with varied compositions (55–68 SiO2 wt%) entrain crystal cargo while ascending through colder, low-silica rocks. Thus, some primary melts at Taranaki volcano are significantly more silica-rich than arc basalts commonly invoked as parental magmas. Further, thermometric and hygrometric constraints preclude a deep crustal hot zone for the source of these melts, which we argue are of subcrustal origin.

Abstract: The Central Asian Orogenic Belt (CAOB) represents a Late Paleozoic archipelago. Yet the crustal growth, reworking and exhumation of individual microcontinental massifs remain poorly constrained. Here, we utilize the Axi epithermal deposit to examine continental preservation and exhumation of CAOB in the Chinese Western Tianshan. Zircon U-Pb dating and geochemistry demonstrate that the andesitic host rock formed by incremental addition of magma in an Andean-type magmatic arc setting at 362, 354 and 342 Ma. Pyrite Re-Os data and textural evidence reveal two mineralization events at 355 and 332 Ma. Zircon (U-Th) /He data reveal temperatures of c. 180 °C until 317.8 ± 9.8 Ma, which is interpreted to record the timing of exhumation of the andesite and gold orebodies prior to their burial by Carboniferous aged sediments. Further sedimentary concealment continued until the Late Mesozoic, when the system was re-exhumed between 148.6 ± 8.6 and 120.0 ± 13 Ma at a rate of c. 9.8 m/Ma as shown by apatite (U-Th) /He data . Collectively, the geo-/thermochronology demonstrates that the Chinese Western Tianshan records the transition from compressional to extensional tectonism during the Late Paleozoic and the Late Mesozoic. The shallow epithermal mineralization was protected from erosion by post-mineralization deposition.

The metamorphic conditions of the Natal Metamorphic Province (NMP) have been the focus of previous studies to assist with Rodinia reconstructions but there are limited constraints on the age of metamorphism. We use a combination of modern techniques to provide new constraints on the conditions and timing of metamorphism in the two southernmost terranes; the Mzumbe and Margate. Metamorphism reached granulite facies, 780–834 °C at 3.9–7.8 kbar in the Mzumbe Terrane and 850–892 °C at 5.7–6.1 kbar in the Margate Terrane. The new P and T constraints are supportive of isobaric cooling in the Margate Terrane as previously proposed. Peak metamorphism of the two terranes is shown to have occurred ~40 million years apart, which contrasts strongly with previous assumptions of coeval metamorphism. While the age of peak metamorphism of the Margate Terrane (1032.7 ± 4.7 Ma) coincides with the tectonism and magmatism associated with the emplacement of the Oribi Gorge Suite (ca. 1050–1030 Ma), the age of metamorphism of the Mzumbe Terrane (987.4 ± 8.1 Ma) occurs ca. 30–40 Myrs after tectonism is previously thought to have finished. We propose that models of advective cooling during transcurrent shearing can explain the metamorphic conditions and timing of the NMP.
