  5. The 1911 Soil Survey got it right in describing the site as ---high organic content silt loam.--- However, the 1959 soil survey called the site peat. (Web site)

Deposited

  1. Loess Unconsolidated, deposited silt and dust. (Web site)
  2. Gravel, sand, and silt, commonly stratified, deposited by glacial meltwater. (Web site)

Relative Proportion

  1. In unconsolidated aquifers, groundwater is produced from pore spaces between particles of gravel, sand, and silt.
  2. Soil texture refers to the relative proportion of sand, silt and clay in the soil. (Web site)
  3. Soil texture Texture is the relative proportion of sand, silt and clay of the dominant soil for each soil map polygon.
