The Geology of Diamond Deposits
May 2019 by Chris Ralph
New theories have been developed and they may lead to new discoveries and give prospectors some new insight on where to look for diamonds.
The fact that mineral deposits can contribute specific types of heavy minerals is why the analysis of the heavy mineral concentrates in the streams of an area can be an important prospecting technique for finding undiscovered mineral deposits.
A bill was introduced and passed by the House of Representatives earlier this year that should make the exploration and opening of a mining operation faster and easier.
The placer deposits of Utah occur in two distinct types of environments. These are 1) placers found adjacent to, and derived from, gold, silver and base-metal deposits; and 2) placers found in major rivers and derived from unknown, distant 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.
Common thought is the switchback slows the velocity of the rushing water and gold drops out from the cut bank to a fill gravel bar within or below the switchback. I am not going to disregard that model; however, I hope to improve upon it.
The Gold Rush in California called hundreds of thousands of souls to leave their homes to journey to the the far reaches of the West. At first the rich goldfields of the Sierra Nevada beckoned to these adventurous pioneers.
Three homonyms come to mind when I think of gemstones, gold and vegetables: carrot, carat and karat. Let’s look at carrot first.
