A discrete surface, or zone of discrete surfaces, with some thickness, separating two rock masses across which one mass has slid past the other and characterized by brittle deformation. Fault is a map-scale feature. When observed in outcrop, some faults are just big breccia/gouge zones with no discrete surfaces, sometimes they are breccia/gouge zones bounded by discrete fault surfaces, sometimes a discrete surface in relatively unbroken rock (at the scale of description).

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: . |
