mineral found in quartz veins
Quartz Vein - an overview | ScienceDirect Topics
The pyrite vein and quartz vein samples from the Dapingzhang area were produced from the copper–lead–zinc–sulfur polymetallic sulfide deposit, which is in the town of Dapingzhang, Lantsang area, Pu'er, Yunnan Province. A few pure lump ores from the pyrite veins and quartz veins were used as raw materials and crushed to 0.5–1 mm. Pure pyrite was picked from a

Quartz: Mineral information, data and localities.
In most environments quartz crystals are attached to the host rock and only have one tip, but double-terminated crystals are also found. As a rock-forming mineral, quartz commonly occurs as sub-millimeter to centimeter-sized anhedral grains, well-formed crystals are uncommon. Secondary vein-fillings of quartz are typically massive.
