Summary:
Name Hancock Formation is proposed in this report for a predominantly siliciclastic sequence overlying the HETERPSTEGINA zone (Tatum Limestone) and underlying the Pensacola Formation in several wells in southern Hancock Co., south-central MS. No thickness given. The Hancock represents uninterrupted neritic sedimentation in the coastal and offshore areas during the late and middle Miocene, while Zones N4b to N8 are missing onshore due to a major regression. Unit correlates with the Tampa Formation of FL as described by Marsh (1966) and is characterized by concentrations of UVIGERINA sp.
