Evidence for polybaric fractional crystallization in a continental arc: Hidden Lakes mafic complex, Sierra Nevada batholith, California by Lewis, Madeline J., Bucholz, Claire E., Jagoutz, Oliver E.

“…Here, we present field and petrographic observations, geochronology, and geochemistry of the Hidden Lakes mafic complex in the central-eastern Sierra Nevada batholith. Our results show that the complex comprises norites, gabbros, monzondiorites, and monzonites that record fractional crystallization of a hydrous (~ 3 wt% H2O), non-primitive basalt within the upper crust (0.3 GPa) at c. 95–96 Ma. …”
