The primary purpose of this investigation was to determine the presence or absence of pre-Pennsylvanian strata in the central part of the Sandia Mountains, along their western scarp. No strata older than Pennsylvanian were found by the author in this area.

The strata present in the Sandia Rim include the upper clastic member of the Sandia formation and part of the lower gray limestone member of the Madera limestone, both of Pennsylvanian age.

The Sandia formation is a predominantly clastic unit of sandstone, shale, limestone, and conglomerate which rests unconformably on a profound erosion surface formed on the Precambrian Sandia granite. The formation ranges in thickness from about 175 to 300 feet. The sediments were deposited in a transitional to epineritic environment under unstable to stable self conditions. A micro-paleontologic and paleontologic study of this formation indicates that the lowermost exposed units are not older than Pennsylvanian.
