The Cenozoic Era

Cenozoic The Quaternary (Pleistocene to Recent) The Quaternary period was shaped by some many events. However, the Ear was characterized by interglacial arrangements. Three periods marked the Cenozoic Era; Paleogene, Quaternary, and Neogene. However, the Cenozoic era was characterized by climatic changes. This accounts for the rich agricultural deposits in Ohio. As a result, the land is adequate for landfill exploration. Consequently, Ohio soil contains huge amounts of fossils, silt, clay sand, and gravel. The weathering process during the Cenozoic era accounted for the huge mineral deposit in Ohio. The dominant sedimentary deposits include chemical and siliciclastic. However, fossil deposits formed layer beds in the southern, northern, and

Evidence of the Mississippian period includes the outcrop on the western edge of Ohio, inconsistence strata deposits in eastern Ohio, deltaic and marine depositions. However, the siliciclastic rocks characterized the sediment deposits during the Mississippian era. The rocks include dolomite, sandstone, ironstone, marine shale and clay. The Mississippian period recorded sandstone deposits, shale, silt, and limestone in East-central Ohio. Devonian Limestone deposits were the major even in the Ordovician period. However, the climatic condition during the Ordovician period favored sediments disintegration. As a result, seabed were eroded with marine shale and fossiliferous sediments. Consequently, huge carbonate deposits in the Ohio Shale marked the era. The Devonian period was characterized by shale and limestone deposits in Central, northeastern and western Ohio. Silurian The Silurian period was characterized by poor fossil preservation. The Silurian era indicated seawater evaporation, shale formation and carbonated materials. Consequently, the western region of Ohio had dolomite, sandstones, limestone, and

Cambrian Mineral materials, fossils extract, sandstone, dolomite, and other sediments were found in the western and southern regions of Ohio. However, the Paleozoic era can be categorized into sis division. The divisions can be identified by specific events. The divisions include Silurian, Devonian, Mississippian and Pennsylvanian and Ordovician periods. Consequently, the Permian period recorded sandstone deposits, coal, dolomite, silt, and limestone in Southeastern Ohio.

Precambrian The era marked the extinction of large mammals that rely of favorable climate conditions. Many geologists termed the Mesozoic era as the age of dinosaurs. However, the early stage began with the growth of angiosperms, flowering plants, and creeping
