Iron formations (IF) represent an iron-rich rock type that typifies many Archaean and
Proterozoic supracrustal successions and are chemical archives of Precambrian seawater …

The ubiquity of Au-bearing arsenian pyrite in hydrothermal ore deposits suggests that the
coupled geochemical behaviour of Au and As in this sulfide occurs under a wide range of …

Transient appearances of oxygen have been inferred before the Great Oxygenation Event
(GOE)[∼ 2.3 billion years (Ga) ago] based on redox-sensitive elements such as Mo and S …

The emergence of oxygen-producing (oxygenic) photosynthesis fundamentally transformed
our planet; however, the processes that led to the evolution of biological water splitting have …

Although studies have proposed that iron oxide-apatite (IOA) deposits may represent the
deeper roots of some Andean iron oxide copper-gold (IOCG) systems, their genetic links …

A comparative in situ LA-ICP MS trace-element study on pyrite from three different, variably
auriferous, Archaean to Palaeoproterozoic palaeoplacer deposits in the Ouro Fino Syncline …

This article examines the geological evidence for the rise of atmospheric oxygen and the
origin of oxygenic photosynthesis. The evidence for the rise of atmospheric oxygen places a …

Redox-sensitive detrital grains such as pyrite and uraninite in sedimentary successions
provide one of the most conspicuous geological clues to a different composition of the …

Mass-independent fractionation of sulfur isotopes (MIF-S) in Archaean sediments results
from photochemical processing of atmospheric sulfur species in an oxygen-depleted …
