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 slopes.
