SUMMARY OF THE STRATIGRAPHY, SEDIMENTOLOGY, AND MINERALOGY OF PENNSYLVANIAN AND PERMIAN ROCKS OF OKLAHOMA IN RELATION TO URANIUM-RESOURCE POTENTIAL

摘要

Pennsylvanián-Permian strata in Oklahoma, were deposited in environments which ranged from deep marine to alluvial fan. The former was most common in the Ouachita geosyncline during Early Pennsylvanián, but parts of the Anadarko basin were also relatively deep water during Middle and Late Pennsylvanián. Alluvial-fan deposits in Oklahoma are related primarily to the Amarillo-Wichita-Criner, Arbuckle, and Ouachita uplifts.nAs a result of erosion of the Wichita and Arbuckle areas during the Pennsylvanian-Permian, Precambrian and Cambrian felsic igneous rocks were exposed and be¬come sources of significant quantities of feldspar in the sandstones and conglom¬erates, especially those on the flanks of the uplifts and possibly sources of significant uranium concentrations in basinal waters. The Ouachita uplift, Sierra Grande-Apishapa uplift to the northwest, and possibly the Appalachian system also furnished feldspar to form the rather common subarkoses in the Upper Pennsylvanian-Permian.
