Petrophysics and mineral exploration: a workflow for data analysis and a new interpretation framework

As mineral exploration seeks deeper targets, there will be a greater reliance on geophysical data and a better understanding of the geological meaning of the responses will be required, and...

Dating hypogene iron mineralization events in Archean BIF at Weld Range, Western Australia: insights into the tectonomagmatic history of the northern margin of the Yilgarn Craton

This study is the first to constrain the absolute timing of hypogene iron mineralization in Archean BIF located in the Yilgarn Craton. In situ SHRIMP U–Th–Pb g...

Iron deposits hosted by banded iron-formations in the Yilgarn Craton: Products of sequential iron enrichment by magmatic, marine and meteoric fluids

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 deeper magnetite...

Protracted evolution of the Marañón Valley Au Belt magmatic complex in the Peruvian Andes using zircon oxygen isotopes, Lu-Hf and U-Pb analyses

The Marañón Valley, located in the Eastern Cordillera of the northern Peruvian Andes, represents a 160-km-long section of the continental margin that was mainly active
during the Paleozoic. A combination of whole rock geo-chemistry, and U-Pb, O and Hf isotop...

Contemporaneous formation of vein-hosted and stratabound gold mineralization at the world-class Dead Bullock Soak mining camp, Australia

We investigate the relative and absolute timing associated with the formation of the world-class Dead Bullock Soak (DBS) mining camp. The study area is situated in the Paleoproterozoic Granites-Tanami Gold Province in the Northern Territory, Australia, and consists of five orog...
