23/07/2019 The low concentration of gold in the amphibolites and metadolerites show that these rocks do not host any gold mineralization but must have played a role in the gold mineralization process. It is suggested that gold-bearing mafic magmatic rock was metamorphosed into amphibolite and metadolerite, with the partitioning of Fe-oxide, rutile and Fe-rich biotite in the gold grains during

Harlequin Gold Mine, Norseman, Dundas Shire, Western

Hosted by metadolerite and metabasalt, most of the gold is found in sub-horizontal veins up to 1.5m thick, with sub-vertical tension veins common around the lode also carrying some gold. Sericite-biotite extends laterally 12m and calcite 20-25m from the lode veins. Inconsistent gold mineralisation also occurs in the biotite zone.

Morphological and chemical assessment of alluvial gold

01/06/2019 Gold chemistry indicates interaction of the mineralization with basic rocks notably amphibolite and metadolerite in the area. The wide compositional span of Ag indicated that gold mineralization in the area resulted from multiple source deposit.

Application of bulk fluid volatile chemistry to

Abstract Disseminated gold (Au) deposits hosted in metasedimentary rocks present unique exploration challenges because the Au is generally very fine-grained or refractory, and not vein-hosted. Exploration programs in such settings rely on extensive lithogeochemical surveys, lesser structural analysis, and little emphasis on ore-fluid geochemistry.
