AlterationDescription decribes aspects of a geologic unit or earth material that are the result of bulk chemical, mineralogical or physical changes related to change in the physical or chemical environment. Includes weathering, supergene alteration, hydrothermal alteration and metasomatic effects not considered metamorphic.
A soil profile description would have to be constructed as a GeologicUnit with unit parts representing the various horizons in the profile.
Thickness of a weathering profile can be delivered as unitThickness of an AlterationUnit.
