Support for our model is provided by relations at Bau in eastern Malaysia, Bingham in Utah, and elsewhere, combined with geologic, chronologic, and metallogenic observations from the three principal alignments of gold-bearing deposits in Nevada. The proposed model has important exploration implications, and can be
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, hosted by stratabound breccia bodies (fig. 29),

Apr 24, 2017 Apr 24, 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.
Sep 06, 2019 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 fools 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.
