Mylonitization in the lower plate of the Buckskin-Rawhide detachment fault, west-central Arizona: Implications for the geometric evolution of metamorphic core complexes

► We present microstructural data from the Buckskin-Rawhide metamorphic core complex. ► Miocene mylonitization conditions were uniform across 35 km in the slip direction. ► Mylonites initiated as a subhorizontal shear zone. ► The mylonite shear zone was captured and exhumed by a NE-dipping detachment fault.
