Pascagoula and Hattiesburg formation (MSMIph;0)

State	Mississippi
Name	Pascagoula and Hattiesburg formation
Geologic age	Miocene
Lithologic constituents	Major Unconsolidated > Coarse-detrital > SandSandy clay and sand. Unconsolidated > Fine-detrital > ClayGreenish and bluish-green clay. Minor Sedimentary > Clastic > SiltstoneGray siltstone and sand, locally fossiliferous.
Comments	Secondary unit desrciption from USGS Lexicon website (MS002) and MS003: A maximum 4,900-ft-thick Miocene sequence underlies younger sandy-clayey alluvial-paralic deposits in MS. In absence of clearly definable and correlatable litho- or biostratigraphic horizons to bracket them, application of formation names, previously assigned to paralic-alluvial intervals (Oligocene to Miocene Catahoula Formation, Miocene Hattiesburg and Pascagoula Formations, and Pliocene Graham Ferry Formation; Brown and others, 1944) is unacceptable in MS. In intervals for which a Miocene or Pliocene age cannot be established, the term "undifferentiated Neogene clastics" is recommended. Whenever applicable, the names Pascagoula and Graham Ferry Members of Pensacola Formation are now used. Author follows usage of Otvos (1994).
