TL;DR: In this article, a suite of Proterozoic sediments from China, Australia, and North America, interpreted in the context of data from similar depositional environments from Phanerozoic time, were used to find evidence for inhibited oxidation of chromium at Earth's surface in the mid-Proteozoic (1.8 to 0.8 billion years ago).

TL;DR: Results indicate that ferruginous (anoxic and Fe2+-rich) conditions were both spatially and temporally extensive across diverse palaeogeographic settings in the mid-Proterozoic ocean, inviting new models for the temporal distribution of iron formations and the availability of bioessential trace elements during a critical window for eukaryotic evolution.

TL;DR: In this paper, a suite of trace elements in sedimentary pyrite from marine black shales were quantified to track the primary elemental abundances in coeval seawater.

The Importance of Oxidized Brines for the Formation of Australian Proterozoic Stratiform Sediment-Hosted Pb-Zn (Sedex) Deposits
TL;DR: A two-fold subdivision for stratiform sediment-hosted Pb-Zn (sedimentary exhalative, sedex) deposits is proposed in this paper, based on fundamental differences in the chemistry of the mineralizing brines.

Routine quantitative multi-element analysis of sulphide minerals by laser ablation ICP-MS: Standard development and consideration of matrix effects
Leonid V. Danyushevsky,Phillip Robinson,Sarah Gilbert,Marc D. Norman,Ross R. Large,Peter J. McGoldrick,Michael Shelley +6 more
TL;DR: A calibration standard for quantitative in-situ multi-element analysis of sulphide minerals by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) is described in this article.
