Title: Simpson Group of Arbuckle and Wichita Mountains, Oklahoma

Author(s): Charles E. Decker (2)


A brief review is given of the steps taken in the study of the Simpson which resulted in recognizing it as a group of formations rather than a single formation. Reasons are cited for reducing the number of the formations from the seven temporarily postulated, to five. Eight short tables are included to show the changes in classification, and three tables of columnar sections along one east-west and two north-south sections show the marked variations in the composition and thickness of the Simpson in its outcrops.
