W. C. FALLAW AND OTHERS Figure 1. Location map. Figure 2. Cross-section along strike. EC=Congaree; Ewh=Warley Hill; Es=Santee and equivalent siliciclastics; Edb=Dry Branch. Upper Three Runs Bluff and the two creek sections are hung on top of Warley Hill. Railroad section is hung on base of silicifiedzone. The two creek sections are composites. Vertical exaggeration = 25x. and in other places they are separated by a layer of fine, wellsorted, light gray to white sand up to 4 ft thick. Small shark teeth occur in both clays. The two clay layers are part of the “green clay interval” at SRS described by Root in internal SRS documents and discussed by Dennehy and others (1989) and Snipes and others (1992). A tan clay higher in the section at Upper Three Runs Bluff has been silicified. The upper part of the Santee and correlative siliciclastics may include sediments equivalent to the Gosport Formation of the Gulf Coast (Veatch and Stephenson, 1911; Toulmin, 1977; Nystrom and others, 1990, 1991; Nystrom and Dockery, 1992). The thickness of the Santee and correlative siliciclastics is approximately 35 ft. Each of the sections contains a bed in the Santee interval which is at least partially silicified. The silicified facies was judged not to be a single key bed because it is not parallel with the Warley Hill-Santee and the Santee-Dry Branch contacts (Figure 2). The upper Eocene Dry Branch Formation, a correlative of the Gulf Coastal Plain, is composed of yellow and orange, fine to coarse, moderately to well-sorted sand with abundant tan and yellow clay layers. Its thickness could not be determined.
