A GIS dataset of geological features for the Babiche Mountain 
map area (95C/8), Yukon Territory and Northwest Territories.


Abstract:  The geological map and database are derived from 
regional mapping in the Babiche Mountain (NTS 95C/8) 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 at visited outcrops.  
     The Babiche Mountain map area is situated at the southern end 
of the Franklin Mountains in a foothills physiographic setting.  The 
geology of the area is characterised by sedimentary strata, of 
Late Devonian to Early Cretaceous age, exposed in a series of 
asymmetrical box or kink folds whose geometry is controlled 
largely by the competence of the Carboniferous Mattson Formation.
Structure in the area is dominated by the La Biche and Kotaneelee
anticlines trending approximately north.  Minor faults with less than 
a few hundred metres of displacement are also reflected in the map
pattern.  En echelon folds at the southern end of the Kotaneelee 
Range link the Kotaneelee anticline with the Mount Martin anticline
to the south.  Stratigraphic improvements include the recognition 
of Permian strata above the Mattson Formation informally known 
as the Tika map unit, the assignment of Triassic strata to the Toad 
Formation, and the recognition of the Lower Cretaceous Chinkeh 
Formation.
