description Publicationkeyboard_double_arrow_right Article 2020Publisher:Elsevier BV Funded by:NSERCNSERCAuthors: Omid H. Ardakani; Hamed Sanei; Simon E. Jackson; Ihsan S. Al-Aasm;Omid H. Ardakani; Hamed Sanei; Simon E. Jackson; Ihsan S. Al-Aasm;Abstract This study presents results of laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) elemental analysis of scattered dolomite crystals in the Upper Ordovician Utica Shale of southern Quebec to investigate the geochemical cause(s) of color variation in dolomite fluorescence and its possible relationship to thermal maturity. Utica Shale dolomite crystals show fluorescence zonation under ultraviolet (UV) light, with a shift from higher red/green quotient (R/G) in the crystal core to lower R/G in the crystal rims within dolomite crystal, while the crystal cores and rims R/G consistently increase with increasing thermal maturity. The LA-ICP-MS results show a consistent increase of Fe, Mn, Sr, Pb, and rare earth elements (REE) from crystal cores to rims, while Mg content shows the opposite trend. The decline in Mg content from the core to rim suggests depletion of Mg in the dolomitizing fluids during dolomite growth. Iron and Fe/Mn ratio are the only parameters that varied systematically with Mg content. The negative correlation between the red/green (R/G) quotient and Fe/Mn ratio suggests that temperature likely had an overarching effect on the chemistry of dolomite that ultimately controls the crystal zonation and its optical properties. Our data suggest that dolomite fluorescence can potentially be used as an alternative thermal maturity indicator in mudrocks with low organic content. However, compilation of a larger dataset is required to completely understand the relationship between dolomite R/G quotient and other established thermal maturity indicators.

Mass graves are usually key historical markers with strong incentive for archeological investigations. The identification of individuals buried in mass graves has long benefitted from traditional historical, archaeological, anthropological and paleopathological techniques. The addition of novel methods including genetic, genomic and isotopic geochemistry have renewed interest in solving unidentified mass graves. In this study, we demonstrate that the combined use of these techniques allows the identification of the individuals found in two Breton historical mass graves, where one method alone would not have revealed the importance of this discovery. The skeletons likely belong to soldiers from the two enemy armies who fought during a major event of Breton history: the siege of Rennes in 1491, which ended by the wedding of the Duchess of Brittany with the King of France and signaled the end of the independence of the region. Our study highlights the value of interdisciplinary approaches with a particular emphasis on increasingly accurate isotopic markers. The development of the sulfur isoscape and testing of the triple isotope geographic assignment are detailed in a companion paper [13]. International audience
