Real gold will not scratch a piece of glass, but other minerals that look like gold often do. If your piece of quartz has a corner or edge that looks like gold on it, try scratching this against a piece of glass. If it leaves a scratch, it is not real gold. You can use any piece of broken glass or mirror for this test.
Pictures Of Gold Bearing Rock
Most of the gold that is mined around the world is found in lode sources, also known as hard rock deposits. This is where the gold is actually encased within rocks and must me manually removed from the Earth to extract the gold. The gold bearing material is called ore. Identifying gold bearing ore just by visual inspection can be very difficult.

Mountain ranges like the Himalayas, the Alps, and the Rocky Mountains are some places where we can find rock. Generally, within the earth's crust or tectonic plates. 4. Granite Rock.

Fool's Gold can be one of three minerals. The most common mineral mistaken for gold is pyrite. Chalcopyrite may also appear gold-like, and weathered mica can mimic gold as well. Compared to actual gold, these minerals will flake, powder, or crumble when poked with a metal point, whereas gold will gouge or indent like soft lead.

Quartz: Gold and quartz combine naturally, and that is why gold is often found in quartz rock.Moreover, the pure white color of quartz makes it easier to spot anything mixed in it. The gold in quartz rock value is also similar to that of gold ore. Therefore, when in a gold-bearing area, it is best to first look for quartz.

Lode deposits usually form gold in larger veins, so it should be easier to see. Smaller flecks of gold are more common in placer deposit gold ore, which tends to look like that area's sedimentary rocks. In mineral terms, cleavage is how a mineral breaks when subject to stress on a particular plane. Gold does not exhibit cleavage.

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.
How to Find Gold in Quartz Sciencing
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. It's universally considered the richest of the gold ores out there.
