PDF Gold in igneous sedimentary and metamorphic rocks

Gold analyses were compiled for about 50 rock types of which more than 50 percent are igneous about 30 percent are sedimentary and the rest are metamorphic The analyses for gold made before 1955 tend to be higher than the newer analyses so separate lists are given At present minute amounts ofgold in rocks seem to be best determined by neutron-activation methods of analysis and the...

Gold occurs very commonly in igneous rocks and in fact it can be said that all igneous rocks have gold grains but very thin does not mean that gold is formed there but staying there as a result of erosion of metamorphic or sedimentary The gold present in the magma comes from igneous rocks which upon cooling form new rocks depending on the...
