Dolomite can form as a major mineral component of marlstones and limestones and is an
important sink for magnesium in the marine environment. Dolomite is widely distributed in …

Rare earth element and yttrium (REY) concentrations of carbonates can be used as potential
proxies to trace the geochemistry of precipitating waters and physico-chemical …

Abstract The Cryogenian Period spans two major glaciations, the Sturtian Ice Age (~ 720–
660 Ma) and the Marinoan Ice Age (~ 650–635 Ma), the termination of each of which was …

Neoproterozoic marine dolomite cements represent reliable, albeit complex, archives of their
palaeoenvironment. Petrological and high‐resolution geochemical data from well …

Current cap carbonate formation models invoke a number of different alkalinity sources for
the Neoproterozoic deglacial ocean (eg, weathering alkalinity, hydrothermal alkalinity …

Middle Permian limestone and marl of the Maokou Formation deposited along the eastern
Paleo-Tethys margin (South China) host abundant chert nodules that formed in association …

The formation of black shale-hosted vanadium deposits is controlled by several factors
including metal supply, biological processes, and marine sedimentary environments …

The mechanism of dolomitization has long been debated due to complex sedimentary and
diagenetic conditions. Large-scale dolomite bodies were recently discovered in the Permian …

Limestone marl alternations (LMAs) usually contain abundant amounts of clay minerals. A
set of Permian LMA source rock gas reservoirs controlled by clay transformations has been …

Most previous studies focused on the redox state of the deep water, leading to an
incomplete understanding of the spatiotemporal evolution of the redox‐stratified ocean …
