| Abstract/Notes | The Sacramento Mountains constitute a sharply asymmetrical cuesta at the eastern edge of the Basin and Range province in south-central NM. The escarpment rises abruptly for more than a mile above the desert plains of the Tularosa Basin. From the crest, near 10,000 ft, the surface slopes gently to the Pecos River, 100 mi to the east and 6,000 ft lower.The rugged west-facing escarpment has been carved in an uplifted fault block composed largely of sedimentary rocks having an aggregate thickness of about 8,000 ft. Tertiary sills and dikes of intermediate composition are of local importance. The bedrock strata range in age from late Precambrian to Cretaceous, but almost the entire sedimentary section is of Paleozoic age. The strata are largely the product of marine deposition on a stable shelf area. Most of the pre-Pennsylvanian formations are thin and laterally persistent across much of southern NM, and many are separated by disconformities. The Pennsylvanian and Permian units are thicker, and show greater lateral variability as a result of more tectonic instability and diastrophism than prevailed earlier. |
