==Name Origin==<br />
The Clement Member of the Grand Detour Formation (Templeton and Willman, 1963, p. 86) is named for Clement Station, Ste. Genevieve County, Missouri, which is 7 miles north of the type section.<br />
<br />
==Type Section==<br />
The type section of the Clement Member is located in a ravine 0.5 mile north of the village of Zell (W1/4 34, 38N-8E), where it is 13 feet thick.<br />
<br />
==Extent and Thickness==<br />
The Clement Member is only 1-4 inches thick where locally present in the northern outcrop area. It is 6 feet thick in outcrops near Cape Girardeau.<br />
<br />
==Description==<br />
The Clement consists of purplish gray, medium- to coarse-grained calcarenite. Where thick, it occurs in 2-15 inch beds that are locally cross bedded. It grades to calcarenitic limestone in some areas.<br />
