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.
Gold in Tertiary Gravels
In some places, semi-continuous sections of riverbed can easily be linked in many places to identify the path of the ancient rivers.
Jadeite in California
...two jadeite locations in California have been thoroughly researched by geologists. There are no doubt others that lie in wait.
Alaska's Cripple Creek Mining District
If developed with metal detecting in mind, this virgin ground could be a bonanza for nugget hunting.
Silver and Base Metal Deposits of the Pioche District
The areas that were mineralized with the bedded ore were huge and vast tonnages were indicated, although they had no idea at the time.
Prospecting for Surface Flood Gold Placers on Low and Intermediate Gradient Streams
Sample panning is a very important method used to find the richest parts of a flood gold deposit before setting up equipment and running material.The Significance of Nuggets in Placers
Chances are better that both types of gold did not come from the same source. Let's look at the probable conditions to cause two types of gold in a placer.
Potholes and Other Bedrock Traps
Potholes in bedrock can trap placer minerals and even be glory holes. They are, at least, interesting geologic phenomena, and at best, a treasure trove of gold nuggets.
