Gold Placers in Italy
Gold is a fairly widespread mineral in the Italian Alps and in the Northern Apennines. It is found both in primary mineralization and in past and recent floods.
Gold Depositiion and Gradients of Placer Streams—Part II
The steeper the gradient is, the more potential erosive power to move gold and other bedload sediments, and the more power to remove obstacles to flow.
Gold Deposits of Montana
Historically, Montana has been an important gold producer, in terms of both lodes and placers, and it still produces gold for the prospector today.
