E1--4 to 21 inches; white (5Y 8/1) sand; single grained; loose; uncoated sand grains; many fine roots; strongly acid; clear smooth boundary. (15 to 30 inches thick)
E2--21 to 58 inches; white (N 8/0) sand; single grained; loose; uncoated sand grains; few fine roots; very strongly acid; abrupt wavy boundary. (20 to 60 inches thick)
Bh1--58 to 60 inches; black (5YR 2/1) sand; common medium faint dark reddish brown (5YR 3/2) mottles; weak medium subangular blocky structure; friable; slightly brittle and weakly cemented; most sand grains coated with organic matter; very strongly acid; clear wavy boundary. (1 to 6 inches thick)
Bh2--60 to 70 inches; dark reddish brown (5YR 3/2) sand; many coarse faint black (5YR 2/1) mottles; single grained; very friable and slightly brittle; sand grains coated with organic matter; very strongly acid; gradual wavy boundary. (4 to 30 inches thick)
BC--70 to 80 inches; dark brown (7.5YR 4/2) sand; single grained; loose; most of the sand grains in brown portion are uncoated and sand grains in black portion are coated; many coarse prominent black (5YR 2/1) spheroidal bodies; strongly acid; gradual wavy boundary. (0 to 12 inches thick)
C--80 to 88 inches; gray (10YR 5/1) sand; common coarse distinct black (10YR 2/1) mottles; single grained; loose; strongly acid.
TYPE LOCATION: Sumter County, South Carolina; 10 miles south of Wedgefield via South Carolina Highway 261, 1.5 miles east on local road in Manchester State Forest, site is 500 feet south of road.
RANGE IN CHARACTERISTICS: Solum thickness is 60 to more than 80 inches. Depth to the Bh horizon is 50 to 80 inches. The soil is extremely acid to moderately acid throughout the profile. It is sand or fine sand to a depth of more than 80 inches. The particle-size control section averages less than 5 percent silt plus clay.
The A horizon has hue of 10YR, value of 3 to 5, and chroma of 1 or 2, or it is mixed white and black.
The E horizon has hue of 10YR to 5Y, or is neutral, value of 7 or 8, and chroma of 0 to 2. Thin discontinuous Bh horizons or dark Bh bodies are in the E horizon of some pedons.
The Bh horizon has hue of 5YR to 10YR, or is neutral, value of 2 or 3, and chroma of 0 to 2. The Bh horizon does not turn redder on ignition.
The BC horizon, where present, has hue of 5YR to 10YR, value of 4 or 5, and chroma of 2 to 4. Many pedons have black or dark reddish brown spheroidal bodies.
The C horizon has hue of 10YR or 2.5Y, or is neutral, value of 5 or 6, and chroma of 0 to 4.
COMPETING SERIES: These are the Centenary and Eglin series. Cententary soils have more than 5 percent silt plus clay in the particle-size control section and have a seasonal high water table at 3.5 to 5.0 feet. Eglin soils have chroma of 3 or more in the E horizon. Similar soils in other families are the Echaw, Hurricane, Kureb, Leon, and Lynn Haven series. Echaw soils have a Bh horizon at 30 to 50 inches from the surface. Hurricane soils are somewhat poorly drained and have a seasonal high water table at a depth of 2 to 3. Kureb soils do not have a continuous Bh horizon. Leon and Lynn Haven soils are saturated with water during the wet season.
GEOGRAPHIC SETTING: Rimini soils are on rims around "Carolina Bays" and on broad smooth divides in the Coastal Plain. Slopes range from 0 to 10 percent. The soil formed in marine sands. The average annual precipitation ranges from 45 to 55 inches, the average annual air temperature ranges from 62 to 70 degrees F., and the frost-free season ranges from 230 to 290 days. Rimini soils commonly are on Wicomico, Sunderland, or Coharie surfaces.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing Centenary series, the similar Kureb and Lynn Haven series, plus Lakeland, Murville, Portsmouth, and Rutlege series. Lakeland, Portsmouth, and Rutlege soils do not have a Bh horizon. Murville soils have a Bh horizon below the A horizon.
DRAINAGE AND PERMEABILITY: Excessively drained; slow surface runoff; rapid permeability in the A and E horizons, and moderate permeability in the spodic horozons. These soils have water tables that are at depths of about 4 1/2 feet for a few days each year, but are below 6 feet during most of the year.
USE AND VEGETATION: Native vegetation is blackjack and turkey oak with a few pine. A few areas have been planted to slash and longleaf pine.
DISTRIBUTION AND EXTENT: Coastal Plain of North Carolina and South Carolina, and possibly Florida and Georgia. The series is of moderate extent.
