===Original description===<br />
The Sorento Limestone Member of the Bond Formation (Simon, ''in'' Wanless, 1955, p. 1764).<br />
<br />
===Derivation===<br />
Named for Sorento, Bond County.<br />
<br />
===Other names===<br />
<br />
===History&#47;background===<br />
<br />
==Type section==<br />
<br />
===Type location===<br />
The type section consists of outcrops along the south-flowing tributary of Dry Fork just southwest of Sorento (NE NE 6, 6N-4W) (Kosanke et al., 1960, p. 39).<br />

==Stratigraphic relationships==<br />
In southwestern Illinois the Sorento generally lies 15-20 feet above the Shoal Creek Limestone. In the deeper part of the Illinois Basin the interval is usually 20-40 feet, but locally it may be as much as 100 feet.<br />
<br />
==Extent and thickness==<br />
The Sorento Limestone and the underlying unnamed coal have been recognized throughout much of the Illinois Basin. The Sorento is less than 2 feet thick.<br />
<br />
==Lithology==<br />
The limestone is generally fine grained and medium gray.<br />

==Well log characteristics==<br />
<br />
==Fossils==<br />
It contains an open-marine fauna composed primarily of brachiopods, crinoids, and gastropods.<br />
<br />
==Age and correlation==<br />
The Sorento is tentatively correlated with the Little Vermilion Limestone of northern Illinois.<br />
