...G. Bloomer ABSTRACT A petrologic and paleocurrent study of the Upper Ordovician Schenectady-Frankfort Formations does not support the commonly held supposition that the sediments were derived from the Taconic region of New England-New York. The grain-size distribution, mineralogy, and paleocurrent...

... different portions of the Main Karoo basin (modified after Rubidge, 1995 ; Hancox and Rubidge, 2001 ). Note Normandien Formation, its three sandstone members (Frankfort, Rooinek and Schoondraai) separated by two argillaceous intervals (the “Christina” and “Moorfield plant fossil assemblage zones...

... in the region around Lexington and Frankfort, but north and south of this area the upper formations are progressively eliminated. In the northernmost area of outcrop the Jessamine forms thè top; in the southernmost, the mid-Benson. The Perryville is less widely developed and is overlapped by the Cynthiana over...

.... Beds with soft-tissue preservation at the Beecher's Trilobite Bed site in the Frankfort Shale and the Martin Quarry in the Whetstone Gulf Formation (both Ordovician, New York State) are dominated by the olenid Triarthrus. A bed-by-bed analysis of the sedimentology, taphonomy, paleoecology...

... limestone-dominated units of the Trenton Group to the black and dark gray Utica Shale and the predominantly gray shales of the Lorraine Group ( Fig. 1 ). The Lorraine Group includes the Frankfort Shale and the Whetstone Gulf Formation ( Ruedemann, 1925 ), both of which yield pyritized soft tissues...

... described lithologically at a 10-cm level of resolution to build the 110-m Frankfort composite section from the uppermost Tyrone Limestone that immediately underlies the Lexington Limestone into the lowermost Clays Ferry Formation. A faunal survey was conducted in these sections and the abundances...

... County, a tight hole, stopped in the Ordovician Queenston Formation, The K. Hirsch No. 1, Franklin Township, Delaware County, was drilled to total depth of 5,327 ft. and penetrated the Ordovician Frankfort Formation. There were slight shows of gas in the Oriskany and Herkimer. The Oneida Formation...

...) and McLaughlin et al. (2004) , showing facies distribution through the upper Lexington Limestone, Clays Ferry–Kope Formation, and Garrard Siltstone from central Kentucky (Frankfort–Winchester area) into southwestern Ohio (Oxford area; see Fig. 1B ). Facies gradients from calcarenite to organic-rich brown shale...

... formation. The Perryville, as it was known, is absent from much of the area of mid-Ordovician outcrop in central Kentucky. It is restricted, with minor exceptions, to two areas referred to in this paper as the Danville-Harrodsburg, or southern area, and the Versailles-Frankfort area. The latter area...

... formation, the Frankfort shale (1840, Vanuxem). In sections near by, where the Pulaski is capped by the Oswego sandstone and its base is determined by its fossils, it has a thickness of about 400 feet. The Pulaski has yielded small quantities of gas in Onondaga County. On account of the incomplete...
