The placer mineral identification key is designed to answer this question. It attempts to recognize all the minerals in your gold pan concentrates.
Faults are fractures, breaks and broken zones in the Earth’s crust where one side of the break has moved relative to the other, and they come in many different varieties.

Prospecting for lithium deposits can take a number of different directions, because this metal can be extracted from a variety of geologically differnet sources.
