There must have been some mighty dumb miners where you lived. The one's I

Quartz formed in the Earth's crust, and stayed there. It is light
(compared with gold) and doesn't have an affinity for iron. Indeed, it
continues to form, given the abundance of silicon and oxygen in the
crust and mantle. In bulk, there is no more gold in meteorites than in
the Earth. The
Quartz forms on Earth.

Carl,
The earth's crust is under a continuous process of differentiation by
various processes. By differentiation I mean the separation and
concentration of the various elements. There are probably a multitude of
mechanisms that allow concentration of specific elements, and all three
rock types
John Hendry gave us a good description of gold forming processes but
there is another method. This is the direct deposition of gold that has
been dissolved by biologic processes and not necessarily at higher than
surface temperatures. Here's one article:
