Nature and timing of metamorphism within the San Isabel granite aureole, Wet Mountains, south Colorado , The
The Wet Mountains, southern Colorado, expose Mesoproterozoic metamorphic and magmatic rocks that record the early deformational history of the east-central continental USA. An increase in metamorphic grade from northwest to southeast indicates that these lithologies represent an exposed cross-section through a tilted crustal block. Of particular interest to the geological history of the region are Cu- and Zn-bearing metamorphic rocks adjacent to the San Isabel A-type granite, situated in the southern Wet Mountains. Previous studies of these units have focused on the timing of base metal ...
