MINNIEVILLE SERIES
Soils of the Minnieville series are very deep, well drained and formed in residuum that weathered from hornblende gneiss and hornblende schist of the northern part of the Piedmont Plateau. Slopes range from 2 to 25 percent. Mean annual temperature is about 54 degrees and annual precipitation is
about 41 inches.
TAXONOMIC CLASS: Fine, kaolinitic, mesic Typic Hapludults
TYPICAL PEDON: Minnieville clay loam - cultivated area on a gently sloping ridge crest. (Colors are for moist soils.)
Ap--0 to 8 inches; brown (7.5YR 4/4) clay loam; moderate fine granular structure; friable; slightly plastic, slightly sticky; many fine roots; 1 percent angular quartz gravel; strongly acid abrupt smooth boundary. (0 to 12 inches thick)
Bt1--8 to 29 inches; red (2.5YR 4/6) clay; strong fine subangular blocky structure; firm, plastic, sticky; many fine roots; few distinct continuous clay films on ped faces; 2 percent angular quartz gravel; few fine mica flakes; strongly acid, gradual smooth boundary.
Bt2--29 to 48 inches; red (2.5YR 4/6) clay; many fine and medium strong brown (7.5YR 5/8) and brownish yellow (10YR 6/8) parent material mottles; moderate fine and medium subangular blocky structure; firm, plastic; sticky; many distinct and prominent clay films on ped faces; common Fe-Mn concretions and streaks; 2 percent angular quartz gravel; few fine mica flakes; strongly acid; gradual smooth boundary. (Combined thickness of the Bt horizon ranges from 25 to 60 inches).
C1--48 to 58 inches; red (2.5YR 5/8) clay loam; many medium and coarse yellowish brown (10YR 5/6) and pale brown (10YR 6/3) parent materials mottles; structureless; friable, slightly plastic, slightly sticky; few fine mica flakes; common fine, Fe-Mn concretions and streaks; common soft weathered horneblende gneiss fragments; 2 percent angular vein quartz gravels; strongly acid; gradual smooth boundary.
C2--58 to 85 inches; multicolored in shades of red, yellow, olive and white silty clay loam; structureless; friable; nonplastic, slightly sticky; 20 percent partially weathered (soft) hornblende gneiss fragments; 2 percent angular vein quartz gravel; few fine mica flakes; strongly acid; hornblende gneiss saprolite.
TYPE LOCATION: Prince William County, Virginia, about 1300 feet east of Purcell Road and about 350 feet north of Minnieville Road; on ridge crest in grassland field.
RANGE IN CHARACTERISTICS: Solum thickness ranges from 30 to 60 inches. Depth to bedrock is more than 5 feet. Rock fragments of angular vein quartz range from 0 to 10 percent throughout the profile. Partially weathered hornblende gneiss or hornblende schist fragments are 0 to 10 percent in the A, Ap, E, and upper Bt horizons, and 0 to 25 percent in the lower Bt and C horizons. Mica flakes are few to common in the B and C horizons. Reaction is strongly acid through moderately acid unless limed.
The A or Ap horizon has hue of 5YR or 7.5YR, value of 3 through 5 and chroma of 3 through 6. It is clay loam, silty clay loam, loam or silt loam.
The E horizon, where present, has hue of 5YR or 7.5YR, value of 5 or 6 and chroma of 3 through 6. It is loam or silt loam.
The Bt horizon has hue of 2.5YR or 10R, value of 3 or 4 and chroma of 4 through 8. It is clay, clay loam or silty clay.
The C horizon is commonly multicolored in shades of red, yellow, and white. It is clay loam, silty clay loam, loam or silt loam, in the fine earth fraction.
COMPETING SERIES: These are the
Colleen (T),
Culpeper and
Elioak series. The Colleen soils have rock fragments of anorthosite and formed in material weathered from anorthosite. The Culpeper soils formed in materials that weathered from arkosic sandstones, phyllites, quartzites and schists and contain rock fragments of these. The Elioak soils formed in weathered products of quartz Muscovite schist and do not have hornblende schist fragments.
GEOGRAPHIC SETTING: Minnieville soils are on ridges and sideslopes of the northern part of the Piedmont Plateau. Slope gradients range from 2 to 25 percent. These soils developed in residuum from hornblende gneiss or hornblende schist and other mixed basic and acidic volcanogenic materials. Annual temperature ranges from about 53 to 57 degrees F. Annual precipitation ranges from about 39 to 43 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These are dominantly the
Orenda and
Spriggs and to lesser extent
Buckhall and
Elioak soils. The Orenda soils have less than 10YR colors in their B horizons. The Spriggs have thinner subsoil and lower content of clay. The Buckhall soils have rock fragments of granite or granite gneiss and the Elioak soils have rock fragments of quartz muscovite schist.
DRAINAGE AND PERMEABILITY: Well drained; medium to rapid runoff; permeability is moderate or moderately slow .
USE AND VEGETATION: The largest acreage is used for general crops corn, soybean, hay and pasture. Few areas are used for residential and commercial development. Native vegetation is oak-hickory forest.
DISTRIBUTION AND EXTENT: Northern Virginia and Maryland. The series is of small extent.

SERIES ESTABLISHED: Prince William County, Virginia, 1985.
REMARKS: Minnieville soils were previously included with the Lloyd or Cullen soils. These soils are thermic. The 2/99 revision updates classification to the 8th Edition of Keys to Soil Taxonomy.
Diagnostic horizons and features recognized in this pedon are:
1. Ochric epipedon - zone from the surface to 8 inches (Ap horizon)
2. Argillic horizon - zone from 8 to 48 inches (Bt horizons)
