Abstract

Archean shallow-level lode-gold deposits in Western Australia are located in rocks of prehnite-pumpellyite to lower greenschist facies and are characterized by (1) predominantly brittle shear zones that formed well after volcanism and late in the structural history, (2) breccia-hosted lodes, (3) low-temperature ore and gangue minerals such as silver sulfosalts, stibnite, and precursor chalcedony, and (4) vertical metal zonation of the orebodies. Ore-fluid temperatures ranged from 150 to 325-degrees-C, and a depth of emplacement of
