Direct evidence of the late Paleozoic glaciation of Gondwana from glacial deposits suggests that geographically extensive continental glaciation began some time in the Namurian (Late Mississippian). However, the timing and characteristics of the onset of glaciation are poorly understood because of a lack of reliable paleontological control and ...Date/Time Thumbnail Dimensions User Comment; current: 03:13, 17 July 2008: 1,500 × 1,125 (994 KB): Wilson44691 (talk | contribs) {{Information |Description={{en|1=Mississippian marble in Big Cottonwood Canyon, Wasatch Mountains, Utah.}} |Source=Photograph taken by Mark A.

The continent lay close to the equator, and sequences of shallow-marine limestone and shale were deposited with occasional incursions of deltaic or shallow-marine sandstone.

Sedimentary rocks of Mississippian age form the lower part of a regional aquifer system in the central Lower Peninsula of Michigan. Strata of the Michigan Formation, the Marshall Sandstone, and the Coldwater Shale were subdivided into an aquifer and two confining units on the basis of hydraulic properties. The Michigan confining unit consists of shale, limestone, dolomite, gypsum, anhydrite, and dKenneth S.

Mississippian Muleshoe mud mound west Texas. Mississippian reef-like structures are common in some areas like West Texas and New Mexico. The mounds are primarily made up of mud with some bryozoans. Excellent examples of these structures can be seen in West Texas, New Mexico, England, and New South Wales, Australia.
