Gangue Minerals - What Do They Tell Us?
January 2017 by Chris RalphThere are a large number of different kinds of gangue minerals, and each of them has its own tale to contribute to the story of the chemistry and geology of a deposit.
I’ve been fascinated by iron minerals for many years. So let’s take a look at this very interesting and colorful element.
Narrowing down a closure date will allow you to check the commodity price during that time and possibly confirm that a low price, rather than a lack of ore, was the driving force that closed the operation.
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.
Not all of these slides and debris flows will produce results, but if you search for these while prospecting in your gold producing areas, then you can increase your odds of finding new gold.
Many of the Sixteen to One’s challenges arise from its unusual geology and the pocket characteristics of the ore deposits.
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.
Every time we prospected here we found gold, sometimes some really coarse flakes, but no large nuggets (yet).
