Heavy Sands Mining
February 2013 by Bill RichLately 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.
It also happens sometimes that glaciers will bury valuable placer deposits. This occurs when the glacier goes over the top of an existing placer deposit.
In this article, we’re going to take a look at the minerals that contain gold and silver, and how you as a prospector can identify them in the field.
Some of the wire forms are strange and fantastic, with wires sticking out in twisted, seemingly random directions. Others have deformed crystals and all of them have significant value to collectors.
We import nearly all of our REEs from China, so it’s critical that we find and continue to develop domestic resources of these elements.
For a time uranium was more popular with prospectors than gold, but this is no longer true, and it has been decades since it was common to see individuals armed with Geiger counters out in the field.
Contacts, faults and zones of weak rock are all places that can act as a pipeline to convey gold-bearing fluids, leading to valuable deposits.
In this review of precious and base metal deposits in Arizona, it is apparent that several significant mines and mineral deposits occur in eastern Arizona, and there is considerable potential for new discoveries.
