9 Ore Deposits and Economic Minerals – Mineralogy

Large, visible specimens, like the one seen below in Figure 9.24 are, however, unusual. Most gold and other precious metal ores contain very fine subhedral metal grains, often microscopic. Silver sometimes occurs in a wire-like or arborescent (tree-like) form (Figure 9.25). It also easily tarnishes and so has a gray color in this photo.
