Eight Natural Geologic Signs Pointing Toward Gold. 02 Sep 2011. Sometimes I get asked, The problem is that gold occurs in many types of deposits, and what indicators work great for one type of deposit don''t always work well for another. As an example, in some places the presence of vein quartz on the ground is a valuable indicator, yet I

3/15/2011· Abstract. Tens of gold deposits of different genetic classes (endogenous and exogenous), groups, and types were recognized in cratons, orogenic belts and magmatic arcs of the Transbaikal region and Russian Far East (T and RFE), evaluated to different extents, explored, and prepared (or are being prepared) for exploitation.

Gold Prospecting in the United States Republished from quot Prospecting for Gold in the United States quot a general interest publication of the US Geological Survey by Harold Kirkemo Lode gold Gold ore from the Olinghouse epithermal deposit When gold is found in the rocks where it crystallized it is known as a quot lode deposit quot

Pocket gold is more closely associated with lode gold, but most of these deposits differ because in most cases the gold is extremely localized. Whereas much of the lode gold is mined out of a quartz vein that may travel great distances, pockets are generally gold enrichments found near the surface.

The problem is that gold occurs in so many different types of deposits. The indicators to look for in one place for one type of deposit don''t always work very well for another. As an example, visible vein quartz on the ground is a valuable indicator in some locations, yet I have been to spots where there is so much vein quartz scattered

Placer gold is still found in almost all southwestern deserts, according to former Bureau of Mines engineer George Fansett. "Moving water has been the most potent factor in the formation of placer deposits," he says. "The usual practice is to seek gold by panning along the water courses—stream beds, sand bars, gulches and arroyos.

8/22/2014· Gold Geology and the Natural Indicators that can help you find gold. Not all gold deposits out there have been found and mined. There are still places that contain gold that have never been worked, despite the fact that miners have been searching for gold for hundreds of years now.

In goldbearing country, prospectors look for placer gold deposits where coarse sands and gravel have accumulated and where "black sands" are concentrated and settled in the stream. Typical examples of these types of locations for heavy material accumulations include the inside bends of rivers and streams as well as areas downstream from

Gold is mainly found in two types of deposits: lode (hard rock veins) and placer (surface). Locating the richest gold bearing areas primarily involves research, planning, dedication and funds. In other words, those who study geological surveys, land formations, rock structures and gold prospecting history prior to prospecting may have a better

The principal gold mining areas were: The Springs, Black Ridge, Miclere and many others too numerous to mention. The alluvial deposits cover a large number of goldbearing leads and have yielded many thousands of ounces of gold. They were considered at the time to be the richest and most extensive alluvial gold deposits in Queensland.

The gold deposits are a classic example of the influence of wall rock composition on ore deposition. The major control of mineralisation was the intersection of quartz/calcite veins with beds of pyritic carbonaceous shale (''slates'') containing graphitic ''floors'' within

It''s possible, though, to identify formations of quartz that have embedded gold veins, extract the gold by hand, and sell the raw gold or make jewelry out of it. Unlike placer gold deposits in creeks and streams, aboveground gold veins can''t be readily found in most states, so you''ll need to do some online research to see whether or not

The hydrothermal conditions needed for gold deposits are also right for quartz. Quartz is more plentiful—so most gold deposits contain quartz, but most quartz deposits do not contain gold. Coexisting Rock Types: Most gold ores (and placer gold) contain small amounts of silver, copper, iron, garnet other minerals.
