Eoline formation, here named, includes the marine beds that lie between the apparently nonmarine Cottondale formation (new) and the Coker formation (new). Consists of glauconitic fine- to medium-grained sand and laminated gray clay. Sand and clay beds are lenticular and of doubtful persistence, but upper part is commonly more clayey and lower part more sandy. HALYMENITES borings locally present, chiefly in upper half. Weathered exposures commonly bright rusty red; updip exposures in Cottondale quad chiefly purple and red sand with little or no glauconite and no HALYMENITES. Thickness 50 to 150 ft. In many places, upper contact is abrupt, locally showing as much as 40 ft of channeling and in such places commonly overlain by nonglauconitic sand; at other places, by massive clay of Coker. At such places, contact is undulating surface having about 10 ft of relief. Lignitized logs and macerated plant remains near top have been determined as Upper Cretaceous.

Eoline Member present near the base of the Coker Formation in western AL. Unit is thinly laminated finely glauconitic very fine- to medium-grained sand, silt, and dark-gray carbonaceous and lignitic clay. Age is Late Cretaceous (late Cenomanian-early Turonian).
