Mississippian geology

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 d

Humans subdivide time into useable units such as our calendar year, months, weeks, and days; geologists also subdivide time.
