Summary:Thirty-eight new oxygen isotope analyses indicate that the contact zone of the intrusion rather than the main ring fault was the major pathway for meteoric fluids during cooling of the pluton. delta18O depletions of over 12 per mille correlate with hydrothermal alteration assemblages, indicating that the bulk of the interaction with meteoric fluids took place at low T (200-450 degrees C).
