February 2016 by Chris Ralph. Most prospectors, when they think of hard rock gold deposits, think of quartz containing particles of gold. While gold deposits can be things besides quartz veins, gold is certainly found in the quartz of veins cutting through various types of rocks. Gold in quartz veins occurs as particles and scales scattered ...

24-04-2017 · Quartz. •••. Nastya22/iStock/Getty Images. Gold is most often found in quartz rock. When quartz is found in gold bearings areas, it is possible that gold will be found as well. Quartz may be found as small stones in river beds or in large seams in hillsides. The white color of quartz makes it easy to spot in many environments.

Gold is found widely diffused in nature even though it is one of the scarcer metals. Very commonly, gold occurs as the native metal encased within quartz. Sometimes the gold is in a finely divided state, sometimes in particles of considerable size, as nuggets, grains, scales, plates, threads and wires in quartz rock.

Gold in rock can be difficult to differentiate from chalcopyrite, pyrite and sulfide minerals. There are several key indices. The first is that gold in rock usually has a corner, flat face or a straight edge. It is also malleable if you drag your fingers across whatever it is that you feel is gold, ...

Native gold occurs as very small to microscopic particles embedded in rock, often together with quartz or sulfide minerals such as "fool's gold", which is a pyrite. These are called lode deposits. The metal in a native state is also found in the form of free flakes, grains or larger nuggets [65] that have been eroded from rocks and end up in alluvial deposits called placer deposits .
