Summary

[edit]
Description

Sandstone from the Mississippian of Ohio, USA.

The Allensville Member is one of four stratigraphic units in the Mississippian-aged, siliciclastics-dominated Logan Formation of eastern Ohio. Ascending from the base, they are the Berne Conglomerate Member, the Byer Sandstone Member, the Allensville Member, and the Vinton Member. The Allensville Member is a thin, coarse-grained interval that is reported to be conglomeratic. Very few localities still exist. As of 2019, I have seen this unit at three sites. The samples seen here are from the first Allensville locality I ever visited. There, samples consist of ferruginous, coarse-grained sandstone. These rocks almost look like granulestone, but the grain size is dominantly very coarse sand (1-2 mm). The yellowish-brown coloration is from limonite. The brownish coloration is likely from goethite.
