Ohio's Geologic Past
PreCambrian Period (4.6 B- 542 MYA) -Volcanic Activity and Rifting -Mountain range formed and eroded in this time no living species found -igneous, metamorphic, and metasedimentary rocks very deep in surface -no current productions
Silurian Period (443-416 MYA) -Ohio was dry and 20 degrees south of the Equator. -The shallow sea was making a return -Coral Reefs, Calms, Brachiopods, Chiopods, Cephalopods -Limestone, dolomite, shale, gypsum for surface rocks in the South -Salt and Sandstone in subsurface crushed limestone -Oil and Gas come from limestone in this period
Ohio's Geologic Past
Mississpian (359-318 MYA) -Ohio is in Equatorial latitudes -The seas retreated at this time. -Brachipods, clams, crinoids, fish, large plants -sandstone, silstone, shale, limestone form surface rocks -limestone used in construction
Quatemary (2.6 MYA-Present) -2/3 of Ohio was covered in Glaciers -Large, Ancient animals, and humans lived in this time -glaicial till, clay, silt, sand, gravel -Sand and Gravel compose cement and are aquifers
Where it Comes From
