DPMS workshop Transitions from porphyry to epithermal ore environments Dr. Jeffrey Hedenquist University of Ottawa, Canada Hedenquist and Lowenstern (Nature,1994) Monday October 13th 2014 9h-17h - room 001 Abstract: This course will focus on characteristics of and processes related to some intrusion-centered ore systems. The geochemical transition from porphyry intrusion to surface will be examined, including evidence from active systems. Near the surface, condensation of magmatic vapors creates lithocaps with advanced argillic alteration, whereas only a few of these are subsequently mineralized. Formation of and exploration for these high-sulfidation Au-Cu deposits and their related intermediate-sulfidation veins will be discussed.
