Scale 1:200 000

 

This Geoscience File consists of a map at a 1:200 000 scale covering the Peace River District south of latitude 56 30' (NTS topo sheets 93P and parts of 93I, 93O, 94A and B). The map covers the surface geology of the Peace River coalfield and areas to the east where coal measures form a subsurface CBM resource. Outlined on the map are CBM land sales, experimental schemes, as well as coal leases. The digital file includes additional layers showing the distribution of coal boreholes, isoreflectance contours for the Gething Formation (from Marchioni and Kalkreuth 1992). A coal borehole database (Coalbh_nad83) is included on floppy disk in dbf and csv format.

 

The surface geology map draws on numerous assessment reports and the mapping results of federal and provincial programs in the 1980s and 1990s. It updates the 1978 compilation of the surface geology of the Peace River coalfield and provides a current geologic base for regional exploration planning.

 

A digital database of well formation-tops (Tops_map.dbf) supports the map. The database is a subset of larger datasets maintained by the Oil and Gas Commission (http://www.ogc.gov.bc.ca). The database is a compilation of stratigraphic log picks by various petroleum company geologists over the years. As such it is not standardized, but does provide a first approximation of depths to important stratigraphic markers in the coal-bearing Lower Cretaceous sequence. It can be used together with other databases (e.g. coal borehole and coal reflectance databases) available from federal and provincial archives to assess CBM potential.
