Glossary of Selected Terms • <br />ALLUVIUM - 1) locally derived - unconsolidated mineral material deposited on sideslopes <br />and valley floors by local unconcentrated downsl ope runoff, accompanied somewhat by <br />gravitational forces. 2) stratified-mineral material that has been subjected to <br />appreciable transport in suspension with concentrated water flow and deposited in <br />highly variable layers. <br />ARGILLIC - a subsoil, specifically a 8 horizon, typified by accumulations of clay <br />translocated form the horizons above. The horizon is identified by a <br />subscript letter "t". <br />CALCIC - A horizon of accumulation of calcium carbonate or of calcium and magnesium <br />carbonate. The horizon is identified by the subscript letter "k". <br />COARSE FRACtdENTS - mineral particles or rocks having diameter greater than 2 millimeters, <br />such as gravels, cobbles, channers, and stones. <br />COARSE-LOAMY - generally, a soil textural class having less than 1B percent clay by weight <br />in the fine-earth fraction, and 15 percent or more of the soil particles are fine <br />sand or coarser. Textures are not sandy (see sandy). <br />COLLUVIUM -Soil material, rock fragments, or both moved by creep, slide, or local wash <br />and deposited at the bases of slopes. <br />DEEP - the soil is 40 to 60 inches deep over bedrock. <br />FAMILY - A level of classification in the soil taxonomic system; a group of soils having <br />similar physical and chemical properties that affects their response to management <br />and manipulation for use. <br />FINE - a soil textural class having 35 to 59 percent clay in the fine earth fraction, by <br />weight. <br />• <br />FINE-EARTH FRACTION - that portion of the soil particles which has diameter of less than 2 • <br />millimeters. <br />9-6-27 Revised 05/16/88 <br />
