Abstract: Abstract Multiple sulfur isotope variability in Archean sedimentary rocks provides constraints on the composition of the Earth’s earliest atmosphere. The magnitude and sign of mass-independent anomalies reflect not only atmospheric processes, but also transformations due… read more here.

DOI: 10.1016/j.chemgeo.2019.02.020
Abstract: Abstract A well-preserved sequence, by Archean standards, of mantle-derived metabasalts and metakomatiites forms large parts of the lower Onverwacht Group of the Barberton Greenstone Belt (South Africa). To elucidate the origin of mafic and ultramafic… read more here.

DOI: 10.1016/j.precamres.2021.106325
Abstract: Abstract The Moodies Group of the Paleoarchean Barberton Greenstone Belt (BGB; ca. 3.22 Ga) provides an exceptional window into Archaean sedimentary and magmatic processes interacting with microbial ecology. Its magmatic component, the Moodies Igneous Complex (MIC),… read more here.

DOI: 10.25131/sajg.122.0033
Abstract: Formations on the northwestern flank of the Barberton Greenstone Belt have hosted over 85% of all the gold recovered from the ca. 3550 to 3000 Ma Barberton Supergroup since early discoveries in 1872. This sector… read more here.
