Hydrothermal Ore Deposits Record the Oxygen Isotope Composition of Meteoric Paleo‐Waters in the San Juan Volcanic Field, Colorado, USA

Abstract

Continental hydrothermal systems record meteoric water oxygen isotope compositions over broad space-and time-scales • Isotopic alteration in hydrothermal systems in the San Juan Volcanic Field, Colorado, USA provides a test of this approach • Inverse modeling suggests a decrease in meteoric oxygen isotope ratios between 23 and 15 Ma, consistent with 2-3 km of surface uplift
