Mississippian geology
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 ...Geologic Time Scale. Humans subdivide time into useable units such as our calendar year, months, weeks, and days; geologists also subdivide time. They have created a tool for measuring geologic time, breaking it into useable, understandable segments. For the purposes of geology, the "calendar" is the geologic time scale.Geology of Ohio. The geologic history of Ohio is represented in the rocks, sediments and geography of the landscape we see today. Many volumes have been written about the state's geology and exploration and research continue. Provided here is a brief summary of how Ohio was shaped by dynamic geologic forces.
