Geochemistry in the Carlin with Simon Griffiths

For this episode we read: "The Oil-Bearing, Carlin-Type Gold Deposits of Yankee Basin, Alligator Ridge District, Nevada" (Hulen & Collister, 1999).  Our chat ranges from lithogeochemistry to isotopes to pathfinder elements in the Carlin (Nevada) with Simon Griffiths. More interesting, let's see his path from a young Welsh structural geologist to the proprietor and principal consultant of 3PXS, a UK-based economic geology and geochemistry consulting firm.
