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 at 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 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 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 Permian informal Tika map 
unit above the Mattson Formation, and local recognition of the 
Chinkeh Formation at the base of Lower Cretaceous succession.
