Geology

Host rock:	Battle Formation, Harmony Formation, LU-1 of the Havallah Sequence, Granodiorite of Copper Canyon
Host type:	Sandstone,Conglomerate,Shale,Limestone,Chert,Granodiorite
Structure:	Golconda Thrust fault; Willow Creek Thrust fault, Virgin Fault.
Tectonic:	The Battle Mountain Mining District has been affected by two major thrust-faulting events: the Antler orogeny in late Devonian-early Mississippian, which emplaced rocks of the Roberts Mountain allochthon from the east, and the Golconda thrust during the Permo-Triassic Sonoma orogeny, which emplaced rocks from the west. An autochthonous block of rocks remains at the center of these tectonic events, and it contains the Penn-Perm Battle Formation, Antler Peak Limestone, and Edna Formation, which rocks often form the host rocks for mineralization in many of the Battle Mountain skarn deposits.
Alteration processes:	All rocks have been affected to some degree by contact metamorphism from the associated graniitc intrusions. The Copper Canyon granodiorite
