As high-grade ore deposits become depleted, there is an increasing demand to process
marginal low-grade ores with complex metallurgical challenges. Orebodies can be rich in …

Framboids, microscopic sub-spheroidal aggregates of pyrite microcrystals, are found in
sediments of all ages and framboid size-frequency distributions are widely used to …

Amber from northern Myanmar has been commercially exploited for millennia, and it also
preserves the most diverse palaeobiota among the worlds' seven major deposits of …

The Corg: P ratios of organic-rich facies (TOC> 1%) exhibit considerable variation through
the Phanerozoic, from< 10: 1 in the Permian Phosphoria Formation to> 1000: 1 in some …

Clusters in systems as diverse as metal atoms, virus proteins, noble gases, and nucleons
have properties that depend sensitively on the number of constituent particles. Certain …

Sulfate-driven anaerobic oxidation of methane (SO 4-AOM) in marine sediments commonly
leads to the precipitation of pyrite. It is, however, frequently challenging to unequivocally …

The Daqiao gold deposit is hosted in organic-rich Triassic pumpellyite-actinolite facies
metamorphosed turbidites in the West Qinling orogen, central China. Gold mineralization is …

Pyrite, or iron disulfide, is the most common sulfide mineral on the Earth's surface and is
widespread through the geological record. Because sulfides are mainly produced by sulfate …

Here we review published studies on the abundance and diversity of terrestrial rock-hosted
life, the environments it inhabits, the evolution of its metabolisms, and its fossil biomarkers to …

ABSTRACT A novel, anaerobically grown microbial biofilm, scraped from the inner surface
of a borehole, 1474 m below land surface within a South African, Witwatersrand gold mine …
