DOI: 10.1007/s00126-020-00986-6
Abstract: The Nimbus Ag–Zn(–Au) deposit is a hybrid VHMS deposit with epithermal characteristics formed in the Eastern Goldfields Superterrane, Yilgarn Craton, under shallow water (~ 700 mbsl), low-temperature conditions. Intersections of some ore lenses are high-grade and polymetallic,… read more here.

DOI: 10.1016/j.oregeorev.2019.103251
Abstract: Abstract Mesoarchean Algoma-type BIF in the Yilgarn Craton are locally enriched by secondary processes to iron concentrations approaching 72 wt% Fe. While their near-surface goethite–hematite ores are unequivocally the product of supergene fluid alteration, their… read more here.
