Enrichment of Mineral Deposits by Weathering—Part II
April 2016 by Chris RalphWhile both zinc and lead deposits also are enriched by the surface weathering process, in part two we will look at the enrichment process for copper and also gold deposits, and at the interpretation of leached outcrops to figure how rich the concentrated deposits below them may be.
...this county contained some of the richest placer ground found in all of California and still produces some pretty impressive finds to this day.
Exploration for and prospecting in search of similar deposits should focus on rhyolite bodies located in fluorite-bearing areas.
Until just recently, platinum-group metals (PGMs), especially palladium, had been holding their own on the market. But, Russia has now resumed shipments and it has brought prices down.
These conditions don’t just apply to Alaska and the Yukon; they apply to western Canada and even to the mountainous western United States.
Prospecting for lithium deposits can take a number of different directions, because this metal can be extracted from a variety of geologically differnet sources.
Even though these were some of the earliest placer deposits to be worked, there is still plenty of gold left today—it just takes more work to recover. Knowing about the old locations where gold has been found is the first step to success.
Gold on the bedrock is a good rule of thumb, but not one that is 100 percent effective. There are plenty of exceptions. So, how does a prospector recognize those exceptions?
