Neoproterozoic chemostratigraphy [PDF]
Precambrian Research, 2010 Chemostratigraphy has diverse applications to investigating the rock record, such as reconstructing paleoenvironments, determining the tectonic setting of sedimentary basins, indirect dating, and establishing regional or global correlations. Chemostratigraphy is thus an integral component of many investigations of the ancient sedimentary record.

Chapter 4 Chemostratigraphy and the Neoproterozoic glaciations [PDF]
Geological Society, London, Memoirs, 2011 Abstract Although the pre-glacial Proterozoic isotopic record is poorly constrained, it is apparent that the chemical and isotopic composition of the oceans began to change during the early to mid-Neoproterozoic and experienced considerable fluctuations alongside climatic instability during much of the subsequent Cryogenian and ...

Chemostratigraphy of the Posidonia Black Shale, SW-Germany
Chemical Geology, 2004Abstract During the Toarcian, widespread deposition of organic-rich mudrocks (black shales) occurred across Europe, linked to a 3rd-order sea-level rise. We provide a high-resolution, multi-proxy chemostratigraphic study of the Dotternhausen sections in SW Germany embedded in a stratigraphic and palecological framework.

The δ13C chemostratigraphy of Ordovician global stage stratotypes: geochemical data from the Floian and Sandbian GSSPs in Sweden [PDF]
Gff, 2020 The δ13C chemostratigraphy of five of the seven Ordovician global stages has been published previously but no such data have been available from the Floian GSSP and most of the Sandbian GSSP in Sweden.

Abstract Carbon- and strontium-isotope data from the Mina Verdun, Arroyo del Soldado and Sierras Bayas groups are summarised and discussed. Mn/Sr ratios and δ 13 C versus δ 18 O crossplots for the Mina Verdun Group at its stratotype show that δ 13 C reflects seawater composition.
