The St. Peter Sandstone is a mature quartz arenite that contains little or no silt and clay, except near its perimeter. Lamar (1928; his fig. 10) provided results of grain-size analysis for a number of St. Peter Sandstone samples in which the percent clay ranged from 0 to 5.8, with a mean of about 2.5 percent. Because clay and silt are minor constituents of the St. Peter Sandstone, we calculate net sand thickness.<\/SPAN><\/SPAN><\/P>
