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.
For the prospector, knowing what oxidized hydrothermal alteration looks like in the field is an important exploration tool.
In this review of precious and base metal deposits in Arizona, it is apparent that several significant mines and mineral deposits occur in eastern Arizona, and there is considerable potential for new discoveries.
A few quick calculations show that approximately 11 tons of gold are lost each year just in the manufacture of new cell phones.
We have to remember that the earliest miners were not geologists, but came from a variety of backgrounds. Their survival depended on finding enough gold so they worked hard and adapted to whatever challenges these new areas presented.
Prospecting for lithium deposits can take a number of different directions, because this metal can be extracted from a variety of geologically differnet sources.
There are literally thousands of abandoned wasterock and ore dumps that dot the United States that could hold many tones of strategic metals.
When prospectors and treasure hunters talk of gold in Arizona, it is the Lost Dutchman or Vulture mine they usually think of. The Lost Dutchman gold mine is just that—a myth chalked full of holes that has been embellished over time as any good legend should be.
