A GIS dataset of geological features for the Dendale Lake map
area (95C/15), Yukon Territory and Northwest Territories.


Abstract:  The geological map and database are derived from 
regional mapping in the Dendale Lake (NTS 95C/15) 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 Dendale Lake map area is situated at the southern end of 
the Franklin Mountains in a foothills physiographic setting.  The map
pattern in the area is dominated by a broad syncline centered over 
the La Biche River and rising to the east and west into structurally
imbricated anticlinal features.  The syncline preserves sedimentary
strata of Early Cretaceous age, while the anticlines expose strata of 
Late Devonian to Permian age.  Fold trends in the area vary from 
southeast through south to southwest, and locally interfere with
each other.  Foreland and hinterland verging thrust faults 
associated with the anticlinal features juxtapose the Devonian and 
Carboniferous strata.  The type section of the Lower Cretaceous 
Chinkeh Formation is located in the southeast corner of the map 
area on a tributary to the La Biche River.
