lithodemic unit original
broader
lithostratigraphic unit original
definition Lithostratigraphic unit that lacks stratification
lithogenetic unit original
broader
geologic unit original
definition Geologic unit defined by genesis. The genesis is manifested by material properties, but the material is not the defining property. Example-- alluvial deposits, glacial deposits.

excavation unit original
lithologic unit original
broader
geologic unit original
definition Geologic unit defined by lithology independent of relationships to other units. Denotes a 'kind' of rock body characterized by lithology, e.g. basaltic rocks.
lithostratigraphic unit original
broader
geologic unit original
definition Geologic unit defined on the basis of observable and distinctive lithologic properties or combination of lithologic properties and stratigraphic relationships. Denotes a particular body of rock.

lithodemic unit original
lithotectonic unit original
broader
geologic unit original
definition Geologic unit defined defined on basis of structural or deformation features, mutual relations, origin or historical evolution. Contained material may be igneous, sedimentary, or metamorphic.

magnetostratigraphic unit original

geophysical unit original
definition Geologic unit defined by magnetic characteristics.
mass movement unit original
broader
lithogenetic unit original
definition Geologic unit produced by gravity driven, down-slope displacemnt of material, and characterized by the type of movement giving rise to the deposit, and by how the individual movement types present in the deposit are related in time and space.
pedoderm original
broader
geologic unit original
definition Geologic unit defined based on soil development and character. Pedoderm is not a surface classification unit because soil classification requires knowledge of the soil profile, which always extends some distance beneath the surface.
pedostratigraphic unit original
broader
geologic unit original
definition Geologic unit that represents a single pedologic horizon in a sequence of strata (consolidated or non-consolidated). The presence of an overlying geologic unit is required, but locally the soil horizon may be at the Earth surface (in which case is may be coincident with a Pedoderm).

polarity chronostratigraphic unit original
broader
geologic unit original
definition Geologic unit defined by primary magnetic-polarity record imposed whien the rock was deposited or crystallized during a specific interval of geolgoic time. Kind of chronostratigraphic unit and kind of geophysical unit.
