Buckskin_Harcavar Mnts

Region A - Harquahala-Harcuvar

A1 - 'S' Mountain Window
Exposure of the Hercules thrust - mylonitic alaskite and qtz-dioirte over qutzite and stretched-pebble conglomerate (basal McCoy Mnt Fm) resting unconformably on deformed and metamorphosed Jurassic volcanic, volcanoclastic, and hypabyssal rocks . Mylon. lin. and stretching trend N-S.

A1 - track?

A2 - Hercules Thrust zone
Thrust zone regionally dips gently to the NE, but here has been folded into a NW trending vertical orientation. Walk downsection SW thro Proterozoic crystalline rocks, mostly mylonitic, the Hercules thrust marked by mylonites; Meso. q-f schists, derived from felis volcanic rocks, int, hypabyssal, and seds including ferrug. quzte and calcareous rocks . The sed extend laterally into the strongly pyritic Calcite Mine area. Local andalusite schists = to argillitc alteration zones in the volcanics.
