Soil Parent Material Modes of Deposition

Morainal material deposited by ice: a mixture of boulders, stones, sand, silt and clay.

Colluvial material deposited by direct gravity induced movement: variable deposit ranging from clay to boulders.

Fluvioglacial material deposited by flowing glacial meltwater: mostly sand and/or gravel.

Alluvial material deposited by modern stream water: variable deposit of sand, silt and clay.

Lacustrine material deposited by glacial lake water: mostly silt and clay.

Organic material deposited when accumulation exceeds decomposition: stratified deposit of peat.
