Regional Geology

This geological map and associated information on rock units at or nearby to the coordinates given for this locality is based on relatively small scale geological maps provided by various national Geological Surveys. This does not necessarily represent the complete geology at this locality but it gives a background for the region in which it is found.

Paleozoic

ID: 3187973
Paleozoic sedimentary rocks

Age: Phanerozoic (251.902 - 541 Ma)

Lithology: Sedimentary rocks

Mississippian
323.2 - 358.9 Ma



ID: 2944244
Coldwater Shale

Age: Mississippian (323.2 - 358.9 Ma)

Stratigraphic Name: Coldwater Shale

Description: Kinderhookian series. Secondary unit description from USGS Geologic Names lexicon (ref. MI016):Although the Coldwater has the largest outcrop area of any Mississippian formation, it is inaccessible at most localities. Its exposures are limited to portions of Branch, Calhoun, and Hillsdale Cos in the southern part of the basin and Huron and Sanilac Cos in the Michigan thumb area. The Coldwater conformably overlies the Sunbury and Ellsworth Shales and conformably underlies the Marshall Sandstone. Fossils in the uppermost portion of the Coldwater in the western part of the basin are Osagean in age, but the rest of the formation is Kinderhookian. Maximum thickness is about 366 m in Iosco and Arenac Cos just north of Saginaw Bay, but is generally 305 m in the eastern two-thirds of the basin and thins to about 168 m in the western third. Unit consists predominantly of gray to bluish gray shale. Its clay minerals are chiefly illite and kaolinite with minor chlorite. Other lithologies occur in the Coldwater and their distributions divide the formation into distinct eastern and western facies. In the eastern half of the basin, beds of silty and sandy shale, siltstone and fine-grained sandstone are common, and increase in abundance and coarseness to the west and up section. In the western half of the basin the Coldwater shales are more calcareous and beds of glauconitic, fossiliferous limestone and dolostone occur frequently especially in the middle and upper portions of the formation. Two marker beds can be traced over long distances: the Lime and the Red Rock beds. The Lime occurs throughout the western part of the basin and is commonly 6 to 1 m thick. The Red Rock is more extensive and occurs in all parts of the basin except the extreme northeast. It is typically 3 to 6 m thick and locally reaches 15 m.
