HomeMade DIY HowTo Make Gold Rocks Geology
Updated April 24, 2017 By Jay Motes Gold is most often found in very small amounts mixed with other materials. Experienced gold prospectors rarely look for gold, but rather look for rocks and rock formations that are known to hold gold. Quartz ••• Gold is most often found in quartz rock.

To accurately distinguish gold-bearing rocks and minerals, keep in mind the following: Look at the color, hardness, and geological location. Use a magnifying glass or microscope for closer examination. Perform density, specific gravity, and streak tests in a lab. Be aware of false signals like pyrite or chalcopyrite.

Lode and Placer Deposits Geologic processes concentrate gold into two principal types of deposits: lode (or primary) deposits where gold is deposited by gold-bearing solutions within rock formations; and, placer (or secondary) deposits where gold-bearing rocks are eroded and the free gold is concentrated in stream beds.

Most lode deposits form when heated fluids circulate through gold-bearing rocks, picking up gold and concentrating it in new locations in the crust.. Lode Gold, or Primary Gold Deposits, are usually found in quartz veins and other types of rock formations. This gold is transported there via hot hydrothermal fluids from the Earth's core.

1. Quartz Quartz is classically aligned with gold. The majority of hard rock deposits found appear to occur in quartz, and gold-in-quartz has even taken on a life of its own. The gold that appears in quartz is almost universally native, meaning that it's in a metallic form contained in the crystalline quartz.

Five rocks to look for when gold prospecting are quartz, granite, basalt, schist, and slate. Gold is deposited in them through volcanic hydrothermal activity or rainwater solutions containing minerals and heavy metals like gold. Gold drops out of the solution and is deposited in cracks and crevices.

The rocks that have gold in them are quartz, iron, magnetite, pyrite, and Lead. However, not all will contain gold. They only give you better chances of identifying gold-bearing grounds. Analyzing the rocks' surface, and using topographic maps and geological reports can be useful.
