Class <<FeatureType>> Contact (extends GeologicStructure )

Very general concept representing any kind of surface separating two geologic units including primary boundaries such as depositional contacts, all kinds of unconformities, intrusive contacts, and gradational contacts, as well as faults that separate geologic units.

Permeability of contacts still needs to be modeled; considered out of scope for GeoSciML2.

Bedding measured as discrete surfaces in the case that those are the feature of interest (e.g. individual cross set surfaces for paleocurrent analysis) should be represented here.
