Abstract

The Pennsylvanian strata of North Central Texas are divisible into three main lithostratigraphic units-in ascending order the Strawn, Canyon and Cisco Groups. The Strawn and Cisco are dominated by sandstones and shales, whereas the Canyon comprises alternating limestones and shales with subordinate sandstones. The subdivision of these units into component formations and members is complicated by the broadly lenticular nature of most of the sandstone and limestone bodies. Thus, for instance, shale formations which at one locality may be separated by a limestone formation may, at another locality, where the limestone has changed facies into shale, be in immediate juxtaposition making discrimination difficult if not impossible. These and other problems relating to the taxonomy and genesis of these units are being actively studied by groups from Baylor, Southern Methodist and Texas Christian Universities.
