The Sr, C and O isotopic evolution of Neoproterozoic seawater
TLDR
Sr and C isotope data obtained on stratigraphic suites of well-preserved marine limestone from Siberia, Namibia, Canada, Svalbard and East Greenland provide a relatively detailed first-order record of isotopic variation in seawater through the late Neoproterozoic Era.About:

TL;DR: In this article, a total of 2128 calcitic and phosphatic shells, mainly brachiopods with some conodonts and belemnites, were measured for their δ 18 O, δ 13 C and 87 Sr / 86 S values.

The snowball Earth hypothesis: testing the limits of global change
Paul Hoffman,Daniel P. Schrag +1 more
TL;DR: The recent discovery that late Neoproterozoic ice sheets extended to sea level near the equator poses a palaeoenvironmental conundrum as discussed by the authors, which does not account for major features such as abrupt onsets and terminations of discrete glacial events, their close association with large (> 10&) negative d 13 C shifts in seawater proxies, the deposition of strange carbonate layers (cap carbonates) globally during postglacial sea-level rise, and the return of large sedimentary iron formations.

Strontium Isotope Stratigraphy: LOWESS Version 3: Best Fit to the Marine Sr‐Isotope Curve for 0–509 Ma and Accompanying Look‐up Table for Deriving Numerical Age
TL;DR: An improved and updated version of the statistical LOWESS fit to the marine 87Sr/86Sr record and a revised look-up table (V3:10/99; available from jmcarthur@ucl.ac.uk) is presented in this article.
Journal ArticleDOI
Toward a Neoproterozoic composite carbon-isotope record
TL;DR: In this paper, a correlation scheme for the Neoproterozoic that corroborates radiometric data that indicate that there were three glacial epochs between ca. 750 and 580 Ma was proposed.

Evidence from ophiolites, blueschists, and ultrahigh-pressure metamorphic terranes that the modern episode of subduction tectonics began in Neoproterozoic time
TL;DR: In this paper, the first appearance of ophiolitic graveyards, blueschist facies metamorphic rocks, and ultra-high-pressure terranes was found to indicate that the modern style of subduction tectonics began in Neoproterozoic time.

A Neoproterozoic Snowball Earth
TL;DR: Negative carbon isotope anomalies in carbonate rocks bracketing Neoproterozoic glacial deposits in Namibia, combined with estimates of thermal subsidence history, suggest that biological productivity in the surface ocean collapsed for millions of years.

The chemical evolution of the atmosphere and oceans
TL;DR: Holland et al. as mentioned in this paper reconstruct the chemical evolution of the Earth's atmosphere and oceans using data from a wide spectrum of fields to trace the history of the ocean-atmosphere system.

Variation of seawater 87Sr/86Sr throughout Phanerozoic time
TL;DR: In this paper, a curve of seawater 87Sr/86Sr versus geologic time through the Phanerozoic is presented, which provides a basis for dating many marine carbonate, evaporite, and phosphate samples.
