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.
Most gold-bearing veins in this region are controlled by fractures associated with the Melones Fault, a late Cretaceous structure that is 108 to 127 million years old.
...the area around Eureka, Nevada is well mineralized and seems to have a bright potential for future production of all sorts of metals.
The other opportunity that I see is in seeking unusual types of deposits. Specifically, the prospector would be searching for the stuff no one (or almost no one) is searching for. These deposits are effectively hiding in plain view.
In some places, semi-continuous sections of riverbed can easily be linked in many places to identify the path of the ancient rivers.
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.
The big interest to prospectors thinking about the effect of erosion is not what might happen long into the future, but what they might find in the rivers later this summer when the water levels go down.
