Abstract
Argon dating of hydrothermal muscovite at the Boundary Creek 2 molybdenite occurrence north of Taku Inlet indicates that molybdenite was formed at or later than 59.7±0.1 Ma. This new date, as well as those U-Pb ages of zircons separated from samples of nearby plutons of the Coast batholith, indicate that molybdenum mineralization was coeval with compressional tectonism and is similar in age to many of the molybdenum porphyry occurrences in nearby British Columbia. The Boundary Creek 2 mineral occurrence in the northern part of southeastern Alaska is not related to the Oligocene molybdenite-bearing extensional magmatism of the southern part of southeastern Alaska, as previously hypothesized.
