Abstract

Rocks in the South Mountains are representative of rocks in metamorphic core complexes elsewhere in Arizona. Fabrics in mylonitic rocks indicate extension parallel to the ENE-trending lineation and flattening perpendicular to the gently dipping foliation. The fabric is well dated as Late Oligocene to Early Miocene (25-20 m.y. ago). Mylonitic deformation was followed by more brittle deformation which produced a chloritic breccia that overlies mylonitic plutonic rocks in the NE half of the arch. The chloritic breccia is probably related to normal faulting along a low-angle dislocation surface.A.P.
