Summary:

Tippah sandstone named in northeastern MS for Tippah Co., where it is exposed in broken hills and ridges. Consists of unconsolidated white and yellow sands, gray in places, with glauconite grains. Upper 4 or 5 ft consists of hard fossiliferous, coarsely grained glauconitic sandstone. Thickness of formation 75 to 100 ft. Overlies Porter's Creek formation and underlies Ackerman clays. Top formation of Midway group. Age is Eocene.

Summary:

The Tippah sandstone member has since 1925 been treated as top member of Porters Creek clay. (See C.W. Cooke, 1925: USGS Prof. Paper 140-E, and E.N. Lowe and others, 1928: USGS Water Supply Paper 576.) It is not known to extend south of Tippah Co., MS.

Summary:

Rank reduced to lentil in lower part of Porters Creek clay. Formerly believed to lie at top of Porters Creek and correlated with Naheola formation of AL. However, it is lower stratigraphically than type exposures of Porters Creek. Consists of loose white to yellow glauconitic HALYMENITES-bearing sand with some calcareous ledges, especially at top and bottom. Type locality suggested on south side of valley of Hurricane Creek as none designated previously.
