Magmatism associated with extension, Harrison Pass Pluton, Ruby Mountains, Nevada

Abstract

The objectives of this study are: (1) to describe in detail the Tertiary rock units exposed in the Harrison Pass pluton, (2) to use geochemical and isotopic data to constrain the petrogenesis of Tertiary granitic rocks in this extensional setting, (3) to develop a possible model of emplacement for the Harrison Pass pluton, and (4) to integrate the information gathered in this study of the Harrison Pass pluton for comparison with previous studies in order to gain a better understanding of Tertiary granitic magmatism in the Basin and Range province and how it relates to lithospheric extension and development of metamorphic core complexes.
