International audience; Interpreting the environmental conditions under which ancient microbialites formed relies upon comparisons with modern analogues. This is why we need a detailed reference framework relating the chemical and mineralogical compo

International audience; Owing to their isolated oceanic setting, atoll-type carbonates are well suited for documenting carbonate deposition and diagenesis in oceanic environments away from continental influence. The atoll-type Dalnegorsk limestone (T

Assessing the origin of Sr and Nd isotopes and (REE+Y) in Middle-Upper Pleistocene travertines from the Acquasanta Terme area (Marche, central Italy) and implications for neotectonics

Autor: Umberto Masi, Francesca Castorina, A. Billi

Pleistocene (bedded) travertines from Acquasanta Terme display ranges of Sr and (REE + Y) contents (462–1576 mg/kg and 250–13,789 ng/g, respectively), which are consistent with an evaporitic rock source. PAAS-normalized (REE + Y) patterns may sup

87Sr/86Sr and trace element mapping of geosphere-hydrosphere-biosphere interactions: A case study in Ireland

Autor: Christophe Snoeck, Quentin Crowley, Saskia E. Ryan, Michael G. Babechuk

Publikováno v: Applied Geochemistry. 92:209-224

Geochemical mapping of biosphere variation has wide application to geological, environmental, forensic and archaeological research. The extent to which trace elements may be used to complement strontium isotopes (87Sr/86Sr) for biosphere characterisa
