Digital geologic map of Lawton quadrangle, southwestern Oklahoma

This data set consists of digital data and accompanying documentation for the surficial geology of the 1:250,000-scale Lawton quadrangle, Oklahoma. The original data are from the Geologic Map, sheet 1 of 4, included in the Oklahoma Geological Survey publication, 'Reconnaissance of the water resources of the Lawton quadrangle, southwestern Oklahoma', Hydrologic Atlas 6, Havens, 1977. The geology was compiled by R.O. Fay, in 1967-68 and J.S. Havens, in 1973.

Paleozoic tectonics in the Edna Mountain quadrangle, Nevada

Geologic mapping at scale 1:24,000 of the Edna Mountain 15-minute quadrangle, Humboldt County, Nev., revealed two episodes of pre-Mesozoic deformation that are difficult to reconcile with either the Antler or the Sonoma orogeny. We believe that the older episode predated the Antler orogeny and may be as old as Late Cambrian. The younger episode may have been more localized, predated the Sonoma orogeny, and was probably Late Pennsylvanian to Permian in age. Deformation related to Antler and Sonoma orogenies also occurred. These four episodes suggest that cycles of uplift, folding, faulting, and erosion began early in the development of the southern Cordillera and continued intermittently throughout Paleozoic time. West of the continental shelf was a broad subsiding basin marked by narrow troughs and elongate structural highs which emerged, matured, and diminished at different times. Waxing and waning deformation in various parts of the geosyncline acting upon local "highs" and troughs can explain the seemingly erratic distribution in north-central Nevada of different fades of time-correlative stratigraphic units and structural blocks of Paleozoic age. Telescoping of facies by thrust faulting certainly took place, but large displacements within brief periods are not essential to the validity of the explanation.
