Feb 01, 1990· Resistive goldbearing silicified zones and shallow quartz vein systems are commonly detectable by conventional galvanic or inductive resistivity techniques. Geophysical surveys over a number of epithermal gold deposits are presented, including Bi murraConway (northeast Queensland, Australia), Gold Ridge (Solomon Islands), Ohui (Coro mandel ...
This page is dedicated 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 gold can be such small particles as to be invisible to the naked eye, or as larger aggregates of easy to see blobs, leaves and crystals in cavities in the quartz. The gold fills cracks and spaces in the quartz as the ascending goldbearing solutions infiltrate the existing quartz vein, filling in .
In 1924 an 80pound lot of goldbearing quartz produced 5,000 and in 1928 some 28,000 was mortared out of a chunk of ore weighing 160 pounds. In the mid30''s a "bunch" was discovered that contained about 750,000. The mine was extraordinarily profitable during the twenties and continued to show a very high operating profit during the thirties.
QuartzTourmaline Veins in the Northern Sierra Nevada Area Summer 1991. Tourmalinebearing quartz veins and replacement deposits, commonly copper and goldbearing, are found in unusual concentration in northwestern Nevada and adjacent northeastern California in Triassic and Jurassic arc rocks and in the Cretaceous plutons that intrude them.
Visible gold occurs in small irregular grains and wires in quartz without associated sulfides (fig. 7A) and in pyrite, both in the veins and in the altered schist in shear zones, even where quartz is absent (fig. 7B). Scattered grains are also found in the sulfidebearing schist adjacent to the quartz veins.

quartz or sulphidebearing tuffargillites. Graphite in a finely dispersed state is ubiquitous in both the host and country rocks. The quartz veins vary in colour from black through grey to milky white. The black and grey varieties are often laminated, well brecciated, and carry higher gold values than the white varieties.
Gold can occur in economic grades in Pegmatites are magmas containing granitic type minerals (feldspar, quartz, mica) which cool slowly and thus allow for very large crystals (>) to form. The gold is deposited through gold bearing sulphides carried by the quartz.

Dec 01, 2010· The present study indicated that the alteration zones and quartz veins contain significant gold and silver mineralization in the Garin Hawal area. Furthermore, this area contains alteration zones and quartz veins that exhibit characteristics of world class goldbearing alteration zones, based on structural dimension and mineralization.
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.
Nigeria Amuda,, Danbatta, and Najime, T3 1,2 3Department of Geology, madu Bello University, Zaria, Nigeria Abstract: The study area predominantly consists of metasediments, porphyritic granites with minor amphibolite dykes, quartz vein and quartzofeldspathic intrusions. The metasediments are fractured and folded in places.
Gold production in Nigeria is believed to have started in 1913 and got to its peak from (MMSD, 2010). Gold in the schist belt of Nigeria occur as alluvial and elluvial deposits. Only 510% of Nigeria‟s 12,000kg of reported gold production has come from vein deposits, while the greater part has been from modern alluvial derived
Some goldbearing areas, including national parks, are closed to prospecting. Violations may accrue major fines and in more serious cases, possible jail time. (See Reference 2.) If a goldbearing area is on privatelyowned land, be sure to obtain permission from the .

A short history about the acclaimed Gold Rush: Gold Bearing Quartz is one of the world''s rarest forms of natural gold. It is found underground by hard rock miners in only a few locations in the world. Most of the World''s production comes from a handful of mines in Northern California. This unique formation of very difficult to find "POCKETS" of ...
