Schematic representation of shear-zone setting of low-sulfide gold-quartz veins and related deposits. Mod-ified from Groves and others (1998), and McCuiag and Kerrich (1998). In almost all areas where low-sulfide gold quartz veins are exposed, gold released by erosion is concentrated in placers (Yeend, 1986).

The veins of these intermediate deposits are characterized by milky, coarsely crystalline quartz, in places associated with drusy and crystalline voids, but only rarely showing a comb-type structure. The gold content is found in the form of free gold and gold-bearing simple sulfide minerals such as pyrite or arsenopyrite.

Quartz is a hard, crystalline mineral composed of silica ( silicon dioxide ). The atoms are linked in a continuous framework of SiO 4 silicon-oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO 2. Quartz is the second most abundant mineral in Earth ''s continental crust, behind feldspar.
