sedimentary rock-hosted gold deposits in P.R. China. These breccia bodies are conformable with stratigraphic units in the host rock. An example of this is the Shuangwang gold deposit (Fan, S.C. and Jin, Q.H., 1994), which is a large Carlin-type gold deposit in the Qinling area,
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, slates and some sedimentary rocks like limestone.

Gold in Greenstone Belts. Gold is found in Archean (rocks older than 2.5 billion years) greenstone belts in Australia, southern Africa, and Canada. Greenstone belts are volcanic-sedimentary sequences, which include ultramafic rocks, dolerite, basalt, chert, sandstone, shale, tuff, banded iron-formation and other rock .
Sep 06, 2019· To identify gold inside of a piece of quartz, hold a magnet against the rock. If the quartz sticks to the magnet, then it contains iron pyrite, or fool's gold. You can also try to scratch a piece of glass or unglazed ceramic with the gold portion of the rock. Real gold will not scratch these substances.

Gold in Igneous, Sedimentary, And Metamorphic Rocks By Robert S. Jones GEOLOGICAL SURVEY CIRCULAR 610 Washington J 969
Canadian geology spans four billion years of Earth history. The oldest rocks are preserved in the stable Archean crustal blocks of which the largest include the Superior, Slave, Hearne and North Atlantic cratons. These blocks are also the repository for much of Canada's gold.

(See Reference 1.) Various hypotheses exist on how gold is formed as it surfaces in numerous types of volcanic and sedimentary rocks. Gold is mainly found in two types of deposits: lode (hard rock veins) and placer (surface). Locating the richest gold bearing areas primarily involves research, planning, dedication and funds.
Much of the Gold mined is from large mining operations where the Gold is smeltered for commercial use, and although many commercial gold mines exist, mineral specimens and crystals are hard to come across. China and South Africa have been the worlds two largest Gold producers, but collectors will rarely if ever see a Gold specimen from these countries due to the restrictive nature of the ...
