California Gold vein formation, Rich gold quartz ore

Rickard has called attention to the especial abundance of gold at the intersection of small quartz veins in Tuolumne and Calaveras counties, California, and to the occurrence of a particularly rich pocket in the Rathgeb mine, San Andreas, where a small vein was faulted a few inches, and where the gold was associated wi…

Antique Gold in Quartz Cufflinks – The Three Graces

This pair of difficult to find antique American cufflinks has been made using ovals of quartz with veins of 14k yellow gold running throughout. One stone displays the natural vein of the quartz. During its cooling and solidification process, veins of gold sometimes became trapped with the crystals of quartz.

Vein (geology) – Wikipedia

For this reason, veins within hydrothermal gold deposits are no longer the exclusive target of mining, and in some cases gold mineralization is restricted entirely to the altered wall rocks within which entirely barren quartz veins are hosted.

Gold Among all the metals on earth there is only one that stays forever shiny and never grows old. It is deposited in the earth's crust in mineralized hydrothermal veins. Silica, known as quartz, is the primary host rock for gold.

Gold Mineral – Uses and Properties – GEOLOGY.COM

White "vein quartz" with gold from Colorado. Vein quartz with gold attached to basalt from California. Although there are about twenty different gold minerals all of them are quite rare. Gold occurs in hydrothermal veins deposited by ascending solutions.

Formation of Lode Gold Deposits

Ores bearing native gold consist of grains or microscopic particles of metallic gold embedded in rock, often in association with veins of quartz or sulfide minerals like pyrite. Gold occurs mainly in pyrite- and polymetallic sulfide–quartz vein/veinlet stockworks.

NW Gold – New Brunswick – Projects

The 2012 prospecting program has extended the potential strike length of the gold-bearing system to 580 m with a new discovery of angular quartz boulders with grab samples grading up to 1.86 g/t gold located 480 m south of the original Lavoie discovery SLAM's prospecting team has discovered other boulders and quartz ve…
