..., is a north-trending, west-dipping, low-angle (18 °–24 ° ) normal fault that juxtaposes syntectonic conglomerates and large-rock avalanches of the Miocene Oak City Formation against footwall rocks that have been ductilely, cataclastically, and brittlely deformed. The Oak City strata dip variably to the east...

... is produced from three uranium-mining areas—Karnes, Live Oak, and Duval—named for the counties in which they principally lie. In each area the host rock is different. Marine-beach sandstone of the Whitsett Formation is the primary host rock in the Karnes area, but some ore has been taken from crosscutting...

... of reworking by eolian activity, with late Pleistocene formation of sand dunes continuing until 11,600 yr B.P. within the Western Lowlands. The sedimentological sequence indicates a progressive, stepwise loss of glacial meltwater and coarse sediment supply during the late-glacial interval, resulting...

... of shales and sandstones between the Belle City and Vamoosa formations in central Seminole County (T. 9 N.). Fig. 1. Index map showing location of Seminole County, Oklahoma. Oakes (1951) and Ries (1951) redefined the Vamoosa formation, excluding the lowermost beds which are below...

... are thought to be due to a development of calcareous beds within the zone (undifferentiated on the cross section) from the Wildhorse limestone down to and including the Wann formation. This is similar to the conditions found by Oakes 25 on the surface in southern Osage County. This conclusion has not been...

..., and Stones Switch sandstone members, consists chiefly of bentonitic clays and tuff near the top and sandstones near the base. The McElroy formation consists of the Conquista clay (a new name substituted for the pre-empted name Falls City shale of Ellisor, 1933 ), the Dilworth sandstone, and the Manning clay...
