Exposures within the Tejana Mesa-Hubbell Draw (TM-HD) area of west-central New Mexico (Catron County) represent Late Cretaceous and Cenozoic continental sedimentation and late Cenozoic basaltic volcanism, punctuated by'periods of weathering and erosion. The TM-HD area is located at the southern margin of the Colorado Plateau and along the northern eroded margin of the Datil-Mogollon volcanic field. The Mesaverde Group (Late Cretaceous) is the oldest unit of the TM-HD area and cbnsists of drab-mlored (yellowish brown and gray), carbon-rich coastal plain deposits. The Mesaverde Group is unconformably overlain by fluvial, intermontane basin deposits of the Baca Formation (Eocene) which are in turn conformably overlain by volcanic wackes and claystones of the early Oligocene Spears Formation (basal unit of the Datil-Mogollon volcanic field). In early Miocene time, Oligocene and older rocks were tilted gently to the southeast (one to three degrees dip), beveled by erosion, and then burie.d by volcanic-rich alluvial sediments (Fence Lake Formation) shed northwe'stward off of the volcanic highlands of the Datil-Mogollon field. Basaltic lavas, which now cap high mesas, were erupted onto the alluvial apron from a northeast-trending fault zone (element of Jemez lineament?) which transects the TM-HD area. An anomalous color zone of reddish sandstones and purplish mudstones was found to be stratigraphically situated within the top portion of the normally drab-colored rocks of the Mesaverde Group. This color zone is interpreted to be an oxidation zone formed.in the lower In the Datil Mountains, "C"-shaped alteration fronts exposed at the base of the pre-Baca weathering profile are commonly radioactive, verified as uranium bearing, and sharply defined by greenish-gray chlorite bands (Chamberlin, 1981). These characteristics, interpreted as features of leached uranium roll fronts, have not been observed in "C"-shaped redox fronts at the base of the pre-Baca oxidation zone in the TM-HD area. Until reasons for this difference can be explained, it will be presumed that the probability for discovery of uranium-roll-front deposits in the subsurface of the TM-HD area .is less than that of the Datil Mountains area.

“…Capping the lower andesite group is a rhyolite-latite sequence of extrusive rocks. The two groups are believed to have been separated by a considerable time and erosional break (Jicha, 1954;Jones, 1956;Willard, 1959). The contact is easily recognizable in the Tres Hermanas Mountains and Cedar Range because of an abrupt change in the physical and chemical properties of the rocks between the two groups.…”

Mineral deposits of Luna County, New Mexico

Luna County mines have produced $8.64 million in minerals since the first recorded mining operations in 1876. The bulk of this production has been from lead-zinc-silver ores, but appreciable amounts of manganese, fluorspar, copper, and gold also have been mined. The principal producing districts of the past were the Cooks Peak, Victorio, Tres Hermanas, Little Florida, and Fluorite Ridge. Lesser districts include the Fremont, Florida, and Cedar-Carrizalillo.Mining is now at a standstill in Luna County because of the lack of known deposits that can be operated profitably under present market conditions. The full mineral potential of Luna County cannot be appraised accurately, but many factors point to at least the possibility of moderate-sized metalliferous ore finds in the Victorio, Tres Hermanas, and Cooks Peak districts. The fluorspar and manganese deposits offer promise only on radical improvement in the respective market prices involved.
