Faults are depicted as linear features (shown as polylines) representing a structural contact between geological units; Faults are typically associated with the bedrock theme and identify a plane of movement or failure where a body of bedrock has been fractured and displaced relative to another, by a large-scale process affecting the earth's crust. The data are available in vector format (containing the geometry of each feature linked to a database record describing their attributes) as ESRI shapefiles.
