Calcite and Limestone
February 2017 by Chris RalphThe other distinguishing feature of calcite has to do with its chemistry. Geologists sometimes take a small bottle of dilute hydrochloric acid out into the field with them because calcite reacts with acids to make a bubbly foam.
The holes were overloaded with explosives, but I didn’t know it. I was just a green mining engineer fresh out of school and told to watch as the experienced miners set the charge.
Historically, Montana has been an important gold producer, in terms of both lodes and placers, and it still produces gold for the prospector today.
While 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.
New theories have been developed and they may lead to new discoveries and give prospectors some new insight on where to look for diamonds.
Many prospectors thought that Nevada was all prospected out following all the rich discoveries of the 1860s and 1870s, and what was there to be found had already been found.
This is the intelligent way to start modern prospecting. The value of literary research yields challenging outings, specimens, history and geologic research.
One of the most important things prospectors do is work to figure out where to go prospecting. Along with understanding the basic geology and putting yourself in a favorable area, one of the things a prospector might consider in finding a location to search is the existence of mining belts also known as mineral deposit trends.
