2016 - 2018  Research Sample Focus
Quartz - Hydrocarbon Interaction: The research is currently focused on black hydrocarbon pockets which also contain quartz.  From such pockets we need handful of the hydrocarbon (uncleaned) and a sample of the wall rock uncleaned - preferably from the bottom. If possible a “junk” Herkimer diamond from the same pocket, preferably on matrix with a clear window through the crystal to the matrix. The search for good crystal frost examples is on!! It is possible that there are many different types of crystal frost left behind from the interaction of the quartz fluids with the oil fluids.  I expect there are things out there that will be amazing!  Windows to Matrix Under Herkimer Diamonds: There is a discussion of these types of “ugly” Herkimer diamonds and their importance to research in the blog of 10/09/2018.
