horizon
horizon
1. An informal term used in stratigraphy to denote a plane within a body of strata. This may be at a boundary of lithological change, or commonly the term may refer to a thin, distinctive bed within a lithological unit. See also BIOHORIZON.
2. An interface separating two media with different geophysical properties.
3. In soil, a horizontal layer that can be distinguished from the layers below and (except for the surface layer) above it. Identified by a coding system using a capital letter, sometimes followed by a subscript, such layers are used to diagnose soil types. See SOIL HORIZON.
