In What Rock Formations Can Gold Be Found? Sciencing

Intrusive rock is typically very hard and erodes slowly. This allows the surrounding rock to be worn away by wind and water, leaving only the harder rock in place. Heavy particles, such as gold, are likely to accumulate against the harder rock while the lighter materials are more easily moved away.

These color changes can be an indicator of gold because gold often occurs in altered rocks or along rock contacts. 17) Iron Staining & Gossans. Not all veins produce much quartz.

GEOLOGY OF SEDIMENTARY ROCK-HOSTED GOLD DEPOSITS

sedimentary rock-hosted gold deposits in P.R. China. These breccia bodies are conformable with stratigraphic units in the host rock. An example of this is the Shuangwang gold deposit (Fan, S.C. and Jin, Q.H., 1994), which is a large Carlin-type gold deposit in the Qinling area, hosted by stratabound breccia bodies (fig. 29),

Extracting Gold HowStuffWorks

Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.

Another option is to pan the pulverized rock to remove the rock from the pan and leave the gold.

Eight Natural Geologic Signs Pointing Toward Gold

Rock Contact Zones and Faults: Many quartz veins and other hard rock gold deposits occur in "zones" along faults or at the contact of two different types of rock. Correct Topography: As a general concept, the coarser gold does tend to hang up farther upstream. In the deserts, most of the best residual placers form in areas with moderate to flat
