D
- DefiningStructure
- Describes the related GeologicStructure which defines a DeformationUnit. That is, a geologic unit defined by its deformation character, eg a shear zone.
- DeformationStyleTerm
- A vocabulary of terms to describe the style of deformation, ie brittle (fault, breccia), ductile (shear), brittle-ductile, unknown.
- DescriptionPurpose
- Codes used for the specification of the intended purpose/level of abstraction for a given feature or object instance, ie the reason for the existence of the GeologicFeature.
Values: instance, typicalNorm, definingNorm.
- DeterminationMethodTerm
- This class is an empty placeholder for a vocabulary of terms describing the method used to determine the measured orientation. Users are encouraged to use a vocabulary of terms managed by the CGI vocabularies working group outside of this model.
- DisplacementEvent
- A description of the age, environment and process of a shear displacement event
- DisplacementValue
- Trying to express the displacement on a fault with respect to a planar approximation of its shape
