Auriferous quartz veins in the Hill End goldfield, NSW, Australia, comprise bedding-parallel vein sets and minor extension and fault-controlled veins which are hosted by a multiply deformed, Late Silurian slate-metagreywacke turbidite sequence. Fluid inclusions in quartz, either from bedding-parallel veins or from narrow, steeply N-dipping veins ('leader' veins) indicate a similar range in ...

Vein matter is the mineral mass filling the vein; it may or may not be valuable. The whole may be of value, for example, fluorspar and barite veins. Or the value may be in minerals like gold, silver, copper, and other ores scattered through quartz, calcite, or other mineral forming the main part of the vein matter, the gangue.

What is Quartz? Quartz is a chemical compound consisting of one part silicon and two parts oxygen. It is silicon dioxide (SiO 2).It is the most abundant mineral found at Earth's surface, and its unique properties make it one of the most useful natural substances.

7/29/2019· Hornblende is the typical amphibole mineral in igneous and metamorphic rocks. Look for glossy black or dark green crystals and cleavage fragments forming flattened prisms in cross-section (corner angles of 56 and 124 degrees). Crystals may be short or long, and even needle-like in amphibolite schists.

Quartz belongs to the trigonal crystal system.The ideal crystal shape is a six-sided prism terminating with six-sided pyramids at each end. In nature quartz crystals are often twinned (with twin right-handed and left-handed quartz crystals), distorted, or so intergrown with adjacent crystals of quartz or other minerals as to only show part of this shape, or to lack obvious crystal faces ...

A vein may be defined as an aggregation of mineral matter, more or less tabular or lenticular in form, which was deposited from solution and is of later origin than the inclosing rock. This definition differs from the one found in many textbooks in that no assumption is made as to the origin of the space occupied by the vein or the manner in which the mineral matter was deposited. In the ...

The image to the right shows rock crystals from Mount Ida with a very fine and even striation and a large rhomb-shaped s-face (the shiny face below the crystal's tip). The specimen has another common feature, a milky extension of the left crystal at the base. Sometimes crystals with a relatively large "stem" are sold as "scepters", but technically this is not correct as i) the shape of the ...

Quartz is one of the hardest of minerals registering at around a 7 on the Mohs hardness scale. Chemically, quartz is the most basic form of all the silicates. Quartz is cool to the touch as a result of its high thermo-conductivity nature. The coolness of quartz is the origin of beliefs among early peoples that quartz was permanently frozen ice.

The ore styles primarily comprise auriferous pyrite-arsenopyrite-quartz vein, disseminated pyrite-arsenopyrite-sericite-quartz mineralized slate, and intense mineralized slate breccia. The gold-bearing sulfide-quartz veins have average Au grades up to 13.5 g/t, generally higher than that of mineralized rock in all orebodies of 0.6–2.0 g/t and ...
