Mining Pegmatite Deposits
With successively lower temperatures as the water mixture cools, new sets of minerals are formed and many of those stable at a higher degree of heat became subject to alteration as the temperature progressively moved lower.

Detecting Old Pocket Diggings
Looking around, I could tell that this was an old hand-digging. As I walked around the perimeter of the digging I could see shovel and pick marks scratched on the clean, hard clay and bedrock.
Gold in Quartz
Because quartz and gold may be deposited together across a considerable range of temperatures, not all quartz veins are the same, and there are several different types of gold-quartz deposits.
