Class <<FeatureType>> DeformationUnit (extends GeologicUnit)
GeologicUnit defined by containment of or association with some geologic structure. DeformationUnits may be predominantly brittle, discontinuous deformation, ductile/plastic deformation or a combination of these.
Includes fault zone, which is a body of rock characterized by deformation associated with some ShearDisplacementStructure feature, and mapped as such. If there are many faults contained in the DeformationUnit then these form a FaultSystem, so there is a zero to one association between DeformationUnit and ShearDisplacementStructure, with the ShearDisplacementStructure being either a FaultSystem, DuctileShearStructure or a Fault. The faults are not the geologic unit, the deformed rock is the geologic unit.
A ShearDisplacementStructure may be associated with 0 to one DeformationUnit. Such a DeformationUnit may have 1 or more parts distinguished by different kinds of fault rocks. Zero represents the case in which the DeformationUnit is not mapped or described.
DeformationUnits may also be defined by presence of cleavage, jointing, structures with a particular orientation (e.g. 'southeast-dipping bedding domain').

GeologicFeature

Term(s) that specify the method by which the values for the GeologicFeature were obtained (e.g. point count, brunton compass on site, air photo interpretation, field observation, hand specimen, laboratory, aerial photography, creative imagination...). This corresponds (loosely) to ISO19115 Lineage.
Statement specifies the method that was used to identify the MappedFeature. Examples: . |
