Geometry Type: esriGeometryPolyline

Description: The dataset comprises a province-wide compilation of subsurface lineaments from various literature sources (digital and nondigital) which were geospatially referenced, compiled digitally into ArcView® layers (i.e., shapefiles), and individually tagged with attribute data stored in a database (also accessible on the AGS web site). The literature search used the Geological Atlas of the Western Canada Sedimentary Basin as a reference point, and included all articles published by the specialty journals (CSPG Bulletin and AAPG Bulletin) up to 2018. In addition, the compilation includes faults interpreted by different oil and gas operators based on their seismic studies and provided to the Alberta Energy Regulator (or its predecessors), as well as lineaments interpreted by AGS staff. It is important to realize that the density of wells and published geological information throughout Alberta is highly uneven, therefore the density of the structural features does not necessarily reflect the structural complexity of a certain area, but rather the present level of knowledge. Locations of natural faults in the province are of paramount importance for public safety, environmental protection, and estimating the potential of a variety of resources including petroleum, metallic minerals, groundwater and geothermal. Exploration for a wide range of deposits is critically dependent on knowledge of the location and age of fractures, which may have created structural hydrocarbon traps, acted as pathways for mineralizing fluids and facilitated kimberlite emplacement.
