California Gold vein formation, Rich gold quartz ore

2012-4-15  The veins are quartz and occur along the contact between a grano-diorite and diabase prophyry. They also cut the igneous rocks. Two systems of fissuring are known. The gold is either native or associated with metallic sulphides. The width of the vein seldom exceeds 3 ft. The lode ore occurs in well-defined bodies or pay shoots. W.

Gold in Quartz - February 2016 (Vol. 85, No. 06) -

Quartz veins often fluctuate widely in value, with the richest gold ore occurring in pockets or “bonanzas” as they are sometimes called. In some mining districts the bulk of the gold is found in these rich pockets and the rest of the vein may be nearly barren.

Quartz Vein - an overview ScienceDirect Topics

Chloritised gabbro at the base is overlain by basalt or basaltic andesite which is itself overlain by shale and sandstone. Gold, commonly visible, occurs in quartz veins up to 50 cm thick within the volcanic rocks but is largely confined to veins with vugs, limonite stains, and intense fracturing and local brecciation. Initial workings in adits and shafts gave way to surface hydraulicking of the deeply oxidized and locally

How to find gold in quartz rock specimens

While streams and rivers are great places to look for placer gold, the erosion that occurs typically causes gold found there to be smooth and polished, rather than rough and jagged with quartz attached. Focus your efforts closer to the source, near where the
