Cretaceous and Paelogene Stratigraphy of Forrest County, Mississippi

<p>Extensive investigation has been done on the subsurface geology and structure of Maxie and Pistol Ridge fields of Forrest and Pearl River Counties, Mississippi. However, a comprehensive study has not been done on the whole of Forrest County as, aside from two minor fields, oil and gas plays do not exist elsewhere in the county. This thesis expands on the work done Vellora Foster (1941) to describe the subsurface geology of the county. Electrical logs from 289 wells drilled in Covington, Forrest, Jones, Lamar, Pearl River, Perry, and Stone counties were used to correlate stratigraphic horizons. Detailed Stratigraphic descriptions of Cretaceous and Paleogene strata were compiled 30 well logs across five cross-sections. Subsidence and infilling of the East Mississippi Syncline and Perry Subbasin are constrained to the Late Trinitian to Early Washitan-Fredericksburgian (109-103 my) and the Tayloran to Sabinian (84-52 my), respectively. Initial faulting along the Maxie-Pistol Ridge Fault may have occurred as early as the Trinitian (109 my). A case for continuous deposition across the Mid-Cretaceous Sequence Boundary is supported by well log data from eastern Forrest and western Perry Counties. The Jackson and Vicksburg Group carbonate sediments undergo a facies change along a north-south trend within the study area.</p>
