Name Hosston Formation chosen by Shreveport Geological Society to designate Lower Cretaceous red and gray shales, dolomites, and sandstones above Cotton Valley formation and below Sligo formation. Replaces Travis Peak, as applied to beds older than real Travis Peak of TX. Base of Hosston is placed above highest black shale unit of Cotton Valley formation. It is marked by a basal conglomerate in AR and in northern LA. Formation grades offshore, south of Shreveport area, into fossiliferous dark shales and Limestones, which contain minor amounts of interbedded red shale and sandstone. Thickness ranges from about 800 ft in AR to over 2,000 ft in northern LA and eastern TX.

Three major sand intervals are present in the Hosston Formation of the report area. The uppermost sandstone has been informally named the Booth Sandstone after the discovery well, Florida Gas Exploration #1 Booth, Jefferson Davis Co., MS (Scherer, 1980). The two lower sandstones (ascending) are referred to as Hosston C and Hosston B Sandstones. The Booth contains productive mouth bar sands and non-productive channel sands.
