Summary:
Providence sand is composed of unconsolidated yellow, white, red, and purplish cross-bedded sand, 150 ft thick, forming top subdivision of Ripley formation in Chattahoochee, Stewart, Marion, and Quitman Cos. Overlies Renfroes marl, through gradual transition. Underlies bright-red sand, in which, at a few localities, boulders of fossiliferous siliceous limestone are found, and which are probably Eocene. Age is Late Cretaceous.

Subdivided to include Perote member (new) in lower part. At type locality of Providence, the variegated coarse sand of upper unnamed member is about 144 feet thick and overlies about 40 feet of fossiliferous fine sand of Perote member. In Alabama grades laterally westward into Prairie Bluff chalk. In Alabama, Providence included in Selma group. [Age is Late Cretaceous.]

Summary:
Unit is a "multilithologic, unconformity-bounded formation." The Providence can be traced from central AL to western GA. Internal unconformity divides unit into informal upper and lower members. Underlies Clayton Formation; overlies Ripley Formation. Age is Late Cretaceous (middle and upper Maastrichtian.) [Use of the term Formation rather than Sand was not accepted for USGS usage during manuscript review on 11/05/85.]

Summary:
Providence sand is assigned to the newly named Fort Valley Group, which includes sand and kaolinitic deposits of coastal marine origin in the Fort Valley Plateau region of central Coastal Plain of GA. The Providence overlies the Nakomis Formation (new) and underlies the Marshallville Formation (new).
