This is a low coastal formation in the Carolinas like Penholoway but younger and lower in altitude. It is comprised primarily of unconsolidated, fine-detrital clay. It is described as variegated quartzose sands, argillaceous sands, and clays, 5 m thick at the type section near Socastee Swamp. (Source: USGS South Carolina Geologic Map Data.) The primary soil type in this collection area is classified as Rutlege Series loamy fine sand. Rutlege Series soils are very deep, very poorly drained soils that are sandy, siliceous, thermic Typic Humaquepts.

Soils: The underlying geology of this area is of Eocene origin and characterized as Ocala Limestone. The Ocala Limestone consists of almost pure limestones with occasional dolomites. It can be subdivided into both lower and upper facies with the lower facies composed of a whitish to cream-colored, fine to medium grained, poorly to moderately hard, fossil rich grainstone and packstone. The upper Ocala is white and somewhat weak and poorly sorted. It is extremely fossil rich grainstone, packstone and wackestone and some chert is common in the upper facies.

Soils: The underlying geology of this area is of Oligocene origin and characterized as Catahoula Formation. This formation is extensive and deep in Texas, up to 185 meters thick. In the area of the collection the Catahoula Formation is primarily mudstone and sand. The upper 90-150 meters is mudstone that is tuffaceous, and sandy; also, occasionally, with some bentonitic clay.

The primary soil types in the collection area are classified as Mattex-Iulus complex soils. The Mattex series consists of very deep, somewhat poorly drained, slowly permeable, acidic loamy soils. They formed in loamy and clayey alluvium. These are nearly level soils on flood plains. Slopes range from 0 to 1 percent. The Iulus series consists of very deep, moderately well drained, moderately permeable, soils on flood plains. These soils formed in recent alluvium derived from coastal plain sediments, often containing fine sandy elements and are extremely acidic. The slope ranges from 0 to 1 percent.

Much of this wet “meadow” is dominated by aggressive stands of grasses and members of the sedge family.
Soils: The underlying geology of this area is estimated to be of lower Paleozoic origin and comprised of Peters Creek Schist. This is comprised of chlorite-sericite schist containing interbedded quartzite. Interestingly, this area is very close to and may interface with the adjacent formation of Ultramafic Rocks that includes serpentine, steatite, and other products of alteration of peridotites and pyroxenites.

The primary soil types in the collection area are classified as Hatboro Silt Loam which consists of soils formed in alluvium derived from metamorphic and crystalline rock. They are on flood plains. Slopes range from 0 to 3 percent. Hatboro Silt Loam soils are poorly drained and have a high to very high surface runoff index. These soils are subject to periodic stream overflow, which usually occurs during the winter and spring months. The A and B horizons are moderately acidic to neutral, generally to a depth of 1-2 meters; the C horizon below ranges from a depth of 2-3 meters with uniformly acidic soils.

The primary soil types in the collection area are classified as Russett-Christiana-Hambrook Complex and/or Sassafras and Croom Soils; though, others may intersect and overlay in specific areas. The soils in the collecting area are generally described as a complex series of fluviomarine deposits. The soils range from a thin loam layer at the surface to varying levels of loam to sandy loam and/or extremely gravelly sandy clay loam strata, depending upon geographical location (ie. Hillslope summits, slopes, footslopes, swales, etc.).
