Lithology and environment
| Primary lithology: | gray,red unlithified sandy claystone | ||
| Includes fossils? | Y | ||
| Lithology description: "2'9" Gray and Reddish Orange Variegated Sandy Clay" | |||
| Environment: | marginal marine indet. | Tectonic setting: | passive margin |
| Glacial or sequence phase: | transgressive | ||
| Geology comments: "The Clairborn Group is composed of a transgressive sequence including the Cane River, Sparta, Cook Mountain, and Cockfield (Rainwater, 1982). Cockfield fluvial deposits are also present in this area. The Cook Mountain Formation was deposited during the latter part of the Clairborne stage of the Tejas sequence. It shows a transgression with the influence from the Mississippi and possibly a Ouachita source (McCarley, 1981). The Laramide and Mexican Cordilleran orogens contributed large amounts of sediment to the Gulf throughout the Eocene (Frazier and Schwimmer, 1987)." | |||

Collection methods and comments
| Collection methods: | bulk,sieve,field collection |
| Rock censused: | 14 kg |
| Reason for describing collection: | paleoecologic analysis |
| Collection method comments: "Horizontal bulk samples were collected, disaggregated, sieved, and counted. Forty pounds of substrate were removed from a four inch horizontal layer near each lithological boundary ...These bulk samples were dried and a thirty pound sub-sample was boiled in Quaternary O solution until they disaggregated. The disaggregated sub-samples were sieved through USGS #10 and #14 sieves." | |
| Taxonomic list comments:"To obtain a minimum number of species, bivalve valves were counted and divided by two. A valve was counted if more than one-half of the shell remained or if a majority of the cardinal processes and one-third of the shell remained. Whole gastropods and recognizable spires were counted. For scaphopods the toal length of the species pieces was divided by the average length of the species. Remains of bryozoan colonies were counted as an individual. Solitary corals were counted as one organism if more than one-half of the theca remained.
... A type collection was established from surface samples and identifed using Dockery (1980) and MacNeil and Dockery (1984). This collection was confirmed by David T. Dockery of the Mississippi Office of Geology." | |
