Saprolite-Regolith Taxonomy— An Approximation

  1. North Carolina State University, Raleigh, North Carolina


Properties of earth materials below soil as defined by Soil Taxonomy and above hard rock are important to many land use activities. Although practitioners from several disciplines study and utilize this material in their work, no quantitative system, based on measurable properties of the materials, is available for its classification. Concepts of the various materials are communicated by genetically based names such as alluvium, glacial drift, saprolite and loess, but these terms do not have rigid class definitions. A four-category hierarchical system is proposed for classifying such materials. Concepts of the material's formation are used to guide the structure of the system, but measurable properties are used to define each taxon. Connotative names utilizing a procedure like that of Soil Taxonomy also are proposed for each taxon.
