This page is dedied to the gold that's still attached to quartz, or a host rock. This type of gold is highly desired in the mineral collecting community. Gold/Quartz specimens are in a completely different league of their own. Remember the specific gravity of quartz is times heavier than water, whereas pure gold is times heavier ...
The quartz precipitation is followed by gold precipitation, results in banded veins with each band representing a different phase in the process. Low sulphidation systems typically show a lateral zoning from proximal quartzchalcedony–adularia in mineralized veins, which commonly display crustiformcolloform banding and platy, latticetextured quartz (Robert et al., 2007).

Colloidal gold and silica in mesothermal vein systems Introduction. A model for the deposition and transportation of gold thought the initial crystallisation of amorphous silica, followed by quartz is proposed by Herrington and Wilkinson, (1993). Their theory suggests an explanation for the ubiquitous bulk grade of goldquartz systems.

Goldbearing quartz reefs commonly show extremely erratic and unpredictable grade variation, although gross geological continuity may be good. This type of variation is often described as being nuggety or having a high nugget effect and can be measured quantitatively using the semivariogram. Understanding of geological features such as reef texture and structure will provide improved models ...
· Free gold grains in contact with quartz occurring in veins or at other sites of dilation are rather indiive of gold being precipitated by phase separation (Guha et al., 1991, Walsh et al., 1988). A phase separation is induced by a drop in the fluid pressure when the fluid enters an opening volume.

The gold quartz stone is a naturally occurring veining of gold found in the host quartz rock. For years this material was crushed and the gold was extracted and used in various methods. A few years ago the natural beauty and uniqueness of the material was rediscovered. Gold Quartz and Citrine earrings. 1, Gold Quartz and Citrine Pendant.

Goldbearing quartz veins, Blue Ribbon Mine, Alaska. For this reason, veins within hydrothermal gold deposits are no longer the exclusive target of mining, and in some cases gold mineralisation is restricted entirely to the altered wall rocks within which entirely barren quartz veins are hosted.
Visible gold from this classic local! A dolomitic matrix with pyrrhotite and arsenopyrite hosts a white quartz vein, with minor siderite, within which a, wellformed gold crystal resides in a vug with euhedral quartz and dolomitesiderite crystals accompanied by a vibrant, orangered scheelite crystal.
Quartz representing open space filling can exist in the same vein or vein system with laminated quartz; the contrasting structures, recording original differences in shape and mechanical origin of channelways, have structural significance.
· VP Exploration Dennis Ouellette comments, "This area with flat veins was mined by artisanal miners who collected the nearsurface material and took it to nearby rivers to pan out the free gold. They left the quartz vein material behind. These flat, blanketlike veins vary between 8 cm to 30 cm thick and to date, up to 550 square metres in size.
