Abstract

Southwestern New Mexico is characterized by Basin and Range Physiography. Nearly level bolson plains are interrupted irregularly by linear mountain ranges. Sedimentary rocks ranging in age from Cambrian and recent crop out in the mountain areas. Darton (1916) mapped and described a limestone formation, about 1,000 feet thick, which he named Gym limestone. He thought the Gym was restricted in outcrop to Luna County and was distinct from previously described Paleozoic formations. The Gym was originally thought to be Pennsylvanian in age but later on was regarded as Permian. In the restudy of the Gym limestone was the basis of this thesis it was found that Darton's Gym included Silurian, Devonian, Mississippian, Pennsylvanian, and Cretaceous (?) rocks in addition to some strata of Permian Age.
