The Many Facets of Iron
March 2013 by Bill RichI’ve been fascinated by iron minerals for many years. So let’s take a look at this very interesting and colorful element.
Gold can potentially be found in all the glaciated areas of the Midwest, but to find it in any appreciable amount one needs to look to areas where the gold gets concentrated by more recent water flows.
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.
Epithermal deposits form in the ground at shallow depths. They are popular with prospectors because can yield very rich deposits and they are widespread in the Western US.
The placer mineral identification key is designed to answer this question. It attempts to recognize all the minerals in your gold pan concentrates.
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 developing a mineral property or mining claims, one of the first goals is to identify and quantify valuable deposits. The classic method of doing this is by drilling holes into the ground to sample what is below the surface. The problem is that one or two holes usually are not going to tell you a whole lot...
The specific gravity of chalcedony is 2.58 to 2.64. This is slightly lower than coarsely crystalline quartz because of slight porosity in chalcedony. Being so light, it will easily wash out of a gold pan.
