ABSTRACT
 
A GIS dataset of geological features for the Tika Creek map area (95C/10), Yukon Territory and Northwest Territories.  

Abstract: This geological map and database are derived from regional mapping in the Tika Creek (NTS 95C/10) 1:50 000 scale map area, as part of the Geological Survey of Canada's Central Foreland NATMAP project. Geological features represented by attributed points, lines, and polygons have been compiled into a GIS dataset suitable for stand-alone use, or integration with other data sets. User-defined attributes provide traditional geological map information with greater detail and enhancements such as explicit orientation data and lithologies.
       The Tika Creek map area is situated to the west of the southern end of the Franklin Mountains  in a foothills physiographic setting. The geology of

the area is characterized by sedimentary strata, predominantly terrigenous rocks of Late Devonian to Early Cretaceous in age. A sub-parallel unconformity at the base of Permian is recognized. Lower Cretaceous rock units overlie Permian rock units with a low-angle unconformity. Predominant structures are regional-scale, north- to northwest-trending, west-verging asymmetrical box-like folds. The anticline on the west side of the map area is imbricated by a west-vergent thrust fault, and the southwest dipping limb of the La Biche Anticline is imbricated by two northwest-vergent thrust faults of minor displacement. Interference of differing fold trends creates local culminations within the map area. Stratigraphic improvements include recognition of the informal Permian Tika map unit above the Mattson Formation, and recognition of the Chinkeh Formation at the base of the Lower Cretaceous succession.
