Huachuca Mountains

general geology

The eastern third of the Huachuca Mountains is predominantly Precambrian granite, which lies in unconformable contact with late Precambrian sediments, Bolsa Quartzite, and Abrigo Limestone near the central part of the range.  The western third of the range is a thick section of Cretaceous sediments, including a fairly complete section of Bisbee Group rocks, with several large Laramide dikes and sills present.  A fairly large granite stock, presumably of Triassic or Jurassic age, is exposed in the southern part of the range close to the Mexico border.
