Summary:

Named as the upper formation of the Naco group; derivation not given. Type section [measured] [north of Rain Valley] in Mustang Mountains in NE1/4 sec 15, T20S, R18E, northeastern Santa Cruz Co, AZ. Consists of thin-bedded, varicolored, partly dolomitic limestone. Overlies Concha Limestone. Overlain unconformably at type locality by Cretaceous? conglomerate. Is 390 ft thick in type section. Identified west of Mustang Mountains in Empire [Santa Rita, Sierrita], Tucson, and Waterman Mountains, in the Basin-and-Range province; and at Dunn Springs Mountain, Cochise Co, AZ in Pedregosa basin, where it is 200 ft thick. Fossil Lophophyllid corals, Rhynchonellid brachiopods, Patelloid gastropods, and Nautiloid cephalopods listed; but knowledge of fauna insufficient for precise dating. On basis of stratigraphic position dating is assumed to be Guadalupe? (Permian) in age. Cross sections; measured sections; geologic map.

Drewes, Harald, 1991, Geologic map of the Big Hatchet Mountains, Hidalgo County, New Mexico: U.S. Geological Survey Miscellaneous Investigations Series Map, I-2144, scale 1:24,000


Summary:

Rainvalley Formation. Provisionally extended into Big Hatchet Mountains, Hidalgo County, southwestern New Mexico. Previously mapped as Concha Limestone by Zeller (1960). Limestone and dolomite. Medium-gray, moderately coarse-grained, dolomitic limestone and dolomite; pale-yellowish-brown, cherty, fine-grained limestone. Thickness about 440 feet (130 m). Conformably overlies Concha Limestone (Lower Permian); shown on cross section underlying Glance Conglomerate of Bisbee Group (Lower Cretaceous). Provisionally correlated with Rainvalley Formation of southeast Arizona; may be carbonate-rich facies of Santa Rita Formation of Tovar (1969) and Campbell (1984) of northwestern Chihuahua. Fossiliferous (brachiopods, horn corals). Age is Early Permian.
