The exact minerals formed in the concentrated supergene deposits depends much on the type of country rock around the deposit and the chemistry of the deposit itself, but if conditions are right, this process will form some rich patches of bonanza ore, in some places valued at thousands of dollars to the ton.Operation And Application Of Magnetometers
The technology used in these devices has advanced greatly in the last century. Many different types of physical effects are used to measure these magnetic fields and we will briefly look at some of these.
The Basics of Geophysical Exploration
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...
