Placer gold deposits form via gravity, with the density of gold causing it to sink into trap sites within the river bed, or where water velocity drops, such as bends in rivers and behind boulders. Often placer deposits are found within sedimentary rocks and can be billions of years old, for instance the Witwatersrand deposits in South Africa.

Thus the origin of the material may be igneous or sedimentary, but, whereas the igneous rocks pass directly into serpentine, the sedimentary ones first pass through an intermediate metamorphic stage (hornblende-schists, etc.), and are then converted.
