Summary:
Recent surface and subsurface studies of Catahoula in south-central MS have revealed major problems and misconceptions about Neogene stratigraphy in this part of the Gulf basin. A mappable bounding sequence above the Catahoula-Bucatunna Formation contact does not exist in the study area. The Hattiesburg Formation above the Catahoula appears to wedge out before reaching outcrop. Therefore differentiation between updip sandy gravels of the Catahoula and similar facies of the Citronelle Formation is difficult at best. Study by Cameron and Day (in prep) ascertained that the Catahoula reaches a thickness of 625 ft and has a three-tiered stratigraphy: (a) a basal unit (75-325 ft) composed of sands and subordinate fine-grained facies; (b) a relatively fine-grained middle unit (250-350 ft) composed of silts and clays with discontinuous sand bodies; and (c) an upper unit (175-325 ft) composed largely of sand and gravels. Most are fluvial channel and associated floodplain deposits. An attempt should be made to correlate the Catahoula in MS to that defined by recent studies in LA.

Summary:
In MS, Catahoula Formation overlies the Paynes Hammock Sand. In outcrop Catahoula consists of a up to 600 ft of generally nonmarine to marginal marine (fluvial to deltaic?) partially carbonaceous, varicolored gravel, sand, silt, and clay. Contact with the Paynes Hammock has been reported variously as gradational, disconformably, and conformable. Age of the Catahoula has been disputed as unit contains no age-diagnostic fossils. Assignment depends on nature of contact with the Paynes Hammock. If it is gradational as suggested by MacNeil (1944), then the Catahoula is late Oligocene, in part. If the contact is disconformable, then the Catahoula may be either Oligocene or Miocene, or both.

Overview	Mid-Gulf Coast basin

Summary:
Catahoula of this study has been arbitrarily defined as those sediments found above the Vicksburg limestones, or the Bucatunna Formation, and beneath the Citronelle or terrace deposits of previous workers. Catahoula sediments show a greater degree of induration than those of similar appearance in the area. A mappable contact between the Catahoula and overlying Hattiesburg Formation has never been found and because they are so similar, the authors recommend that they be considered a single mapping unit. The Catahoula crops out in the mapping area, only in the Mize quad. Unit is composed of sandy silt, silt, and clay, interbedded with sandstone layers. The silt and clay commonly display blocky to conchoidal rock fracture. The sandstones are fine-grained. Kaolinite is the dominant clay mineral. Unit also contains mica and smectite. Age is Miocene.

Summary:
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).
