This unit was deposited during the Mississippian about 330 million years ago and is composed of fine to medium-grained limestone, dolomite, sandstone, siltstone, and greenish-gray shale.Eons. The eon is the broadest category of geological time. Earth's history is characterized by four eons; in order from oldest to youngest, these are the Hadeon, Archean, Proterozoic, and Phanerozoic. Collectively, the Hadean, Archean, and Proterozoic are sometimes informally referred to as the "Precambrian."Other articles where Mississippian Subsystem is discussed: geochronology: Completion of the Phanerozoic time scale: … in 1839, was subsequently termed Mississippian in 1870 as a result of work conducted by another American geologist, Alexander Winchell, in the upper Mississippi valley area. Eventually the overlying strata, the coal-bearing rocks originally described from Pennsylvania, were ...The Carboniferous Period occurred from about 354 to 290 million years ago during the late Paleozoic Era.
