The carbonates of the Mississippian are often susceptible to diagentic alteration which makes the porosity values laterally across the area open for high variability ...

Apr 2, 2013 · Mississippian rocks in Kansas can be divided into two general lithologic sequences. The older sequence is a group of shallow-marine limestones, cherts, and cherty limestones that are Kinderhookian, Osagean, and Meramecian in age (fig. 7). Many of the groups of rocks targeted in the Mississippian limestone play are part of that sequence. Archimedes is a fossil that looks like a screw.
