...A. Kay Schrodt; Judith A. Schiebout ABSTRACT The Baca Formation, which crops out discontinuously in east-west-trending exposures from Socorro, New Mexico, to the New Mexico-Arizona border, is composed of fluvial, alluvial-fan, and lacustrine deposits. It was deposited in a basin which formed during...

..., which previously had been mapped in the Hignite Formation, with the Windrock (Fire Clay) coal bed, which defines the base of the underlying Catron Formation, many Pennsylvanian stratigraphic problems are resolved.

...C. H. Dane; A. A. Wanek; J. B. Reeside, Jr. ABSTRACT Winchester’s (1920) Bell Mountain sandstone member at the top of his Miguel formation in the Alamosa Creek Valley area, Socorro and Catron counties, New Mexico, is the upfaulted duplication of his Gallego sandstone member, from which it had been...

... the Sandia, Madera, and Red Tanks formations. This seaway was in existence between Atokan and Virgilian time but was widest during Desmoinesian and Missourian time. Pennsylvanian marine sedimentation was limited on the west by the Zuni positive, on the east by a long sinuous platform west of the Estancia...

Minor oil and gas production has also been established in the Pennsylvanian and Mississippian carbonates in northwestern New...

..., Catron County, New Mexico, topped the Precambrian at 12,146 ft, beneath Abo Formation rocks. No early Paleozoic was reported. The section thins to the west, mainly by loss of the Cretaceous toward southern Navajo County, Arizona, where about 4,500 ft of mostly Paleozoic section is present. Both Devonian...

Two deeper-pool tests were completed in the San Juan basin; one, the Consolidated Oil and Gas Company’s Tribal C-1-6, sec. 6, T. 26 N., R. 3 W., produces gas from the Dakota (Cretaceous) in a pool where shallower Cretaceous formations are already productive. The other...
