Talc (derived from the Persian via Arabic talq) is a mineral composed of hydrated magnesium silicate with the chemical formula H 2 Mg 3 ( SiO 3) 4 or Mg 3 Si 4 O 10 ( OH) 2. In loose form, it is the widely used substance known as talcum powder. It occurs as foliated to fibrous masses, its monoclinic crystals being so rare as to be almost unknown.

The Yilgarn Craton of Western Australia is one of the most gold-endowed geological regions in the world (Aitken et al., 2018; Barnes and Fiorentini, 2012; Blewett et al., 2010b).The gold (Au) and platinum-group elements (PGE) content of the mantle underlying the Yilgarn Craton is poorly constrained, and solely inferred from …

What is talc. Talc is predominantly hydrated magnesium silicate (Mg3Si4O10 (OH)2), and was first used for pleurodesis in 1935 [ 3 ]. Varying amounts of calcium, aluminum, iron, and lead may be present, according to the origin of the formulation. Talc may also contain several mineral contaminants (eg, magnesite, dolomite, kaolinite, …

INTRODUCTION The Mount Fitton area is located approximately 600 km northnortheast of Adelaide, in the northern Adelaide Geosyncline. The area contains talc-mineralisation associated with hydrothermal alteration, and has been used by CSIRO for over ten years as a test site for various remote sensing and geophysical instruments.

Au concentrations were in the order of quartz-biotite schist > talc-chlorite schist > amphibolite >> quartzite, with anomalous concentrations detected in quartz-biotite and talc-chlorite schists. Elevated concentrations also occurred in residual soils overlying quartzite and amphibolite lithologies.
