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. It occurs also in a finely divided state disseminated through schistose rocks
