Tuscaloosa Top Seal Thickness
<DIV STYLE="text-align:Left;"><P STYLE="font-size:16ptmargin:7 0 7 0;"><SPAN><SPAN>The Selma Chalk, which overlies the Tuscaloosa Group is widely recognized as a regional aquiclude. In the Mobile area, it generally ranges in thickness from 300 to 400 m (Raymond and others, 1988; Pashin and others, 1998). There currently is no published thickness map for the Selma Chalk. However, there are published maps of the top of the Selma and Eutaw Formations. (Hinkle and others, 1983; Moffett and others, 1984a). These were gridded and the top Tuscaloosa subtracted to determine the thickness of the Selma Chalk</SPAN></SPAN></P><DIV><P><SPAN /></P></DIV></DIV>
