Genetic implications of regional vs. fracture-controlled fluid flow in carlin-type gold deposits, Nevada

摘要

The ability to identify differences in the chemistry of hydrothermal solutions that formed Carlin-type gold deposits in areas that experienced regional fluid flow in proximity to Eocene igneous rocks (e.g., the Carlin trend) vs. fracture-controlled fluid flow distal to Eocene igneous rocks (e.g., the Getchell trend) was evaluated using fluid inclusion microthermometry, quadrupole mass spectrometer (QMS) gas analyses, and H-isotopes.
