History/background

Type section

Type location

Grimmer (1968) described the type section of the Misenheimer Member as an exposure 3 miles west of Mill Creek (SW NW 35, 13S-2W) in the south branch of a tributary of Cooper Creek.

Reference section

Reference location

Grimmer (1968) designated an exposure on the south bank of Green Creek, 33 feet southwest of Illinois Highway 146, 1.75 miles northwest of Jonesboro (NE NW 23, 12S-2W), where the shale is about 25 feet thick, as a principal reference section.

Reference status

Stratigraphic relationships

The Misenheimer Shale Member of the Lingle Formation overlies the Tripp Member. Both Grimmer (1968) and North (1969) placed the type Misenheimer well above the base of the Lingle (where Savage had placed it), but Grimmer assigned the strata below the Misenheimer to the St. Laurent Formation of Missouri, whereas North subdivided them into the Howardton and Tripp Members of the Lingle.

Extent and thickness

The Misenheimer occurs only in and near the outcrop region in Jackson, Union, and Alexander Counties (fig. D-15).

Lithology

The Misenheimer Member consists of as much as 50 feet of dark gray to gray-brown, calcareous, spore-bearing shale that contains a few macrofossils.
