THE MISSISSIPPIAN
The Age of Crinoids Mississippian named
by Alexander Winchell in 1870 Named for
carbonate rocks deposited in the Upper
Mississippi River valley Lower Carboniferous
in Europe and Canada

23
THE MISSISSIPPIAN
The Age of Crinoids Crinoids abundant Ooids
abundant Clear, shallow marine water Salinity
higher than normal Mississippian Lime Bank
24
THE MISSISSIPPIAN
The Age of Crinoids Late Mississippian the
Kaskaskia sea retreated
25
THE MISSISSIPPIAN
The Age of Crinoids Late Mississippian the
Kaskaskia sea retreated Detrital muds and
limestones formed. Petroleum
reservoirs Nonmarine shales and sandstones
from erosion of Acadian highlands
26
THE MISSISSIPPIAN
The Age of Crinoids Erosion of Acadian highland
produced Pocono Ss. Forms resistant ridges
of the Pocono Mtns. Forms third clastic
wedge
