Calcite and Limestone
February 2017 by Chris Ralph
The 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.Additional articles that might interest you...
The Batteries Metal Rush

There is a major change coming in the economy of the world and now is the time for prospectors and miners to grab a ticket and get on board.
The Goldfield Mining District -- Then and Now
March 2017
In 1983, some of the ore yielded more than 2,500 ounces of gold within 30 feet of the surface. The shoot pinched to a narrow vein.

I am going to keep to the basics of surface indications and visual clues in the rocks and minerals themselves that help me find gold-bearing veins in this classification of deposits.

Diary of a Diamond Prospector
April 2017
I couldn’t wait to get started. With no field budget, an assay budget of $100/year, a 1975-Ford Bronco that was a road hazard, a gas card, a topo map and full support of the director, I headed to the State Line district near Tie Siding along US Highway 287 to begin mapping kimberlite.

Heavy Sands Mining
February 2013
Lately my mind has been involved with group 4 of the transition elements, namely titanium, zirconium, and hafnium. They all have similar chemical properties. Of greatest interest to economic geologists and miners is that these valuable elements often occur together in sands.
