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.
