Background. Artisanal and small-scale miners in Bolivia release on the order of 120 tons of mercury annually. The mercury finds its way to the Amazon with catastrophic consequences for the biosphere. A project aimed at reducing the release of mercury

An early Archaean greenstone belt and mid-Archaean supracrustal rocks in central West Greenland host a number of significant mineral occurrences that have recently been targets for exploration, which has included diamond drilling. Diamond drilling in

In the pre-3,760-m.y.-old Isua supracrustal belt, West Greenland, copper sulfides with minor amounts of pyrrhotite are found in sulfide, silicate, and carbonate facies iron-formation. In oxide facies iron-formation pyrite is the sole sulfide, occurri

FIELD relationships and geochronological data have shown that the metamorphosed supracrustal rocks of the Isua area are the oldest known components of the Archaean complex of West Greenland1–4. Rb–Sr, U–Pb and Pb/Pb ages in the range ∼ 3,700

In the ca. 3.8 b.y.-old Isua supracrustal belt, West Greenland, pyrrhotite and chalcopyrite occur as strata-bound mineralizations in layered tuffaceous amphibolites and in an iron-formation. Mineralizations with more complex mineral assemblages compr
