TL;DR: It is reported that through much of the later Neoproterozoic, anoxia remained widespread beneath the mixed layer of the oceans; deeper water masses were sometimes sulfidic but were mainly Fe2+-enriched, marking a return to ocean chemistry not seen for more than one billion years of Earth history.

TL;DR: In this article, the isotopic fractionation of Mo during adsorption to a range of Fe (oxyhydr)oxides, under variable Mo/Fe-mineral ratios and pH, was investigated.

TL;DR: A trace element study of two Ediacaran-Early Cambrian sedimentary successions in South China is presented in this article, where trace element data are used to determine the palaeoenvironmental and diagenetic conditions during this Early Cambrian interval of metal scavenging that resulted in enrichments over grey shale of Mo > Cd > V > U >Ni > Ag > Zn > Cu > Pb.

TL;DR: In this article, a largely anoxic and most probably sulphidic deeper water body for most of the Nemakit-Daldynian and lower Tommotian is supported by positive δ34S values for sulphide, as well as high degree of pyritization (DOP) and total organic carbon (TOC) values.

TL;DR: In this paper, the authors present a proposal for a unified presentation of Mo isotope ratios in the studies of mass-dependent isotope fractionation, and suggest that the Mo-98/95 of the NIST SRM 3134 be defined as +0.25.
