The Quartz Page: Occurrence

A typical quartz vein gold ore was selected as the sample ore. The main useful mineral is gold, followed by a small amount of silver and pyrite, and the main gangue mineral is quartz. The results of chemical multi-element analysis of raw quartz vein gold (Table 1) and phase analysis results (Table 2) are shown in the following tables.

Veins occur in dacite and limestone, and cross cut bedding and lithological contacts. Most of the mineralization of economic significance is located in quartz veins that average 1 metre to 2 metres wide, but may be significantly wider. The vein fillings consist of quartz, calcite, and locally barite and rhodochrosite.

While the surge of solid quartz countertops is likely a response to the excess of busy, speckled granite we saw everywhere in the early 2000s, we're now seeing a shift back toward center with the rise of countertops featuring less densely packed color variation. The color—which appears in the form of veining that contrasts against the main shade of the stone—is more random and …

Gold mineralization is within a relatively weak quartz vein stockwork with a low sulphide content (mainly pyrite and pyrrhotite). Approximately 200 metres north of the M Zone, the North Walter Lake Zone ("NWLZ") is in a zone of high strain with deformed quartz veins within pillowed to massive mafic volcanic flows.

The quartz veins were formed by the filling of open fissures and display little evidence of significant replacement of wall rock. Milky quartz crystals and associated vein minerals of the Ouachita Mountains were deposited from hot water during the closing stages of mountain building, some 280 to 245 million years ago. The veins attain a maximum

VEIN DEPOSITS

Jul 01, 2006· Quartz veins developed in deep crustal levels (10–12 km) were exhumed after long-lasting uplift and denudation. A similar PT trajectory has been observed in the Neoproterozoic Seridó belt (Cavalcanti de Araújo et al., 2003). Consequently, enrichment in Au is not expected in deeper parts of the quartz veins.
