REGOLITH: Gr. (regos) blanket or cover and (lithos) rock or stone.


“A general term for the layer or mantle of fragmental and unconsolidated rock material, whether residual or transported and of highly varied character, that nearly everywhere forms the surface of the land and overlies or covers the bedrock. It includes rock debris of all kinds, volcanic ash, glacial drift, alluvium, loess and aeolian deposits, vegetal accumulations and soil.” – Jackson, 1997.
