Detailed correlations of ancient glacial deposits, based on temporal records of carbon and strontium isotopes in seawater, indicate four (and perhaps five) discrete ice ages in the terminal Proterozoic Eon. The close and repeated stratigraphic relationship between C-isotopic excursions and glaciogenic rocks suggests that unusually high rates of organic carbon burial facilitated glaciation by reducing atmospheric greenhouse capacity. The emerging framework of time and environmental change… 
C-isotopic stratification in a Neoproterozoic postglacial ocean
We report C-isotopic data from the cap carbonate overlying the terminal Proterozoic Nantuo diamictites in south China. The C-isotopic measurements reveal a large C-isotopic gradient of ∼3‰ along
Neoproterozoic ice ages, boron isotopes, and ocean acidification
The Neoproterozoic Earth underwent at least two severe glaciations, each extending to low paleomagnetic latitudes and punctuating warmer climates. The two widespread older and younger Cryogenian
The sulfur isotopic composition of Neoproterozoic to early Cambrian seawater — evidence from the cyclic Hanseran evaporites, NW India
The sulfur isotopic composition has been determined for terminal Neoproterozoic to early Cambrian evaporites from the Hanseran Group in NW India. δ34S values, ranging from +27.5‰ to +39.7‰ vs. Canyon
C-isotope variations and paleoceanographic changes during the late Neoproterozoic on the Yangtze Platform, China
Abstract This study reports δ13C measurements on the well-preserved and continuous marine carbonate strata of the Donglongtan Formation (late terminal Proterozoic) from southwestern China.
Uncovering the Neoproterozoic carbon cycle
Interpretations of major climatic and biological events in Earth history are, in large part, derived from the stable carbon isotope records of carbonate rocks and sedimentary organic matter.
A neoproterozoic snowball earth
Negative carbon isotope anomalies in carbonate rocks bracketing Neoproterozoic glacial deposits in Namibia, combined with estimates of thermal subsidence history, suggest that biological productivity
Toward a Neoproterozoic composite carbon-isotope record
Glacial deposits of Sturtian and Marinoan age occur in the well-studied Neoproterozoic successions of northern Namibia, South Australia, and northwestern Canada. In all three regions, the Marinoan
Are Proterozoic cap carbonates and isotopic excursions a record of gas hydrate destabilization following Earth's coldest intervals?
Regionally persistent, thin intervals of carbonate rock directly and ubiquitously overlie Proterozoic glacial deposits on almost every continent, and are commonly referred to as cap carbonates. Their
Perturbation of the carbon cycle at the Middle/Late Jurassic transition: Geological and geochemical evidence
A compilation of new and published stratigraphic, paleontological and geochemical data is used to detect the reciprocal influences of carbon cycling and global environmental changes in the Jurassic.
On Cryogenian ( Neoproterozoic ) icesheet dynamics and the limitations of the glacial sedimentary record
The snowball earth hypothesis is a unified theory accounting for the global distribution of Cryogenian (roughly 720 to 635 Ma) glacial and glacial marine deposits, their global synchroneity

Comparative Earth History and Late Permian Mass Extinction
The repeated association during the late Neoproterozoic Era of large carbon-isotopic excursions, continental glaciation, and stratigraphically anomalous carbonate precipitation provides a framework
Carbon isotope evidence for the stepwise oxidation of the Proterozoic environment
TLDR
Trends in the carbon isotope composition of sedimentary organic carbon and carbonate show that during the Proterozoic aeon the organic carbon reservoir grew in size, relative to the carbonate reservoir, mostly during episodes of global rifting and orogeny.
Secular variation in carbon isotope ratios from Upper Proterozoic successions of Svalbard and East Greenland
TLDR
Isotopic compositions of isolated samples from other localities are consistent with a worldwide extended interval of enhanced organic burial and consequent net survival of oxidized material, probably O2, just before the initial radiation of metazoans.

TLDR
It is shown that the decreased isotopic fractionation between marine carbonates and organic matter from the Early to mid-Cenozoic may record variations in the abundance of atmospheric CO2.
