Abstract:
Continental collision along the southern margin of the North American continent during Pennsylvanian time created northwesterly directed compressional stress that was transmitted to the continental interior along boundary faults of the southern Oklahoma and Delaware aulacogens. As a result, numerous basins and uplifts were formed in the aulacogens and edges of the craton, including the Anadarko, Delaware, Midland, and Palo Duro basins, the Amarillo-Wichita uplift, Matador-Red River arch, and Central Basin platform.
The Palo Duro basin is a basement-bounded, or yoked, shallow intracratonic basin filled largely with Pennsylvanian and Permian strata. Its tectonic-depositional history may be divided into four stages: (1) formation of the basin between basement blocks (Matador arch, Amarillo uplift) that were uplifted along boundary faults of the southern Oklahoma aulacogen during Early Pennsylvanian time, and subsequent deposition of basement-derived, fan delta "granite wash" around uplifts flanking the basin; (2) planation and burial of uplifts through Early Permian time, and infilling of the deep basin with shelf-margin carbonate and basinal facies; (3) encroachment of continental red-bed facies from sources in New Mexico and Oklahoma and deposition of thick Middle to Upper Permian marine evaporit s in sabkha environments; (4) marine retreat during Late Permian time and development of a Triassic lacustrine basin brought about as a result of continental rifting and drainage reversal.
