Abstract:
The geological map and database are derived from regional mapping in the
Redfern Lake (NTS 94G/5)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.
Redfern Lake map area encompasses the transition from the
Foothills to the Main Ranges of the Rocky Mountains of northeastern
British Columbia. The Foothills are underlain by late Paleozoic and
Mesozoic rocks that are deformed into long linear folds with minor
thrust faults, all detached on a basal décollement in the underlying
Besa River Formation. The Main Ranges in the western part of the map
area are underlain by lower Paleozoic limestones, dolostones and
quartzites emplaced by large, shallow-dipping thrust faults onto the
Besa River Formation. The dolostones are internally deformed by smaller
thrust faults. The limestones contain tight overturned folds with
penetrative cleavage. Whereas the early Paleozoic rocks are dominated by
thick panels of carbonate rocks, the late Paleozoic and younger units
are dominated by clastic rocks with subsidiary but economically
significant carbonates in the Carboniferous Prophet (Debolt) Formation
and the Triassic Charlie Lake, Baldonnel and Pardonet Formations. Broad
glacially scoured river valleys cut through the ranges. Some of these
valleys are occupied by transverse faults which accommodate differential
shortening and/or structural transitions at depth.
Purpose:
Provided as part of a National Mapping (NATMAP) commitment to compile
Geographic Information System products.
Supplemental_Information: Points, lines, polygons, and attribute
data representing the geology of the area covered by NTS map 94G/5 (1:50
000 scale) in northeastern British Columbia, Canada.
