View GeoFile (PDF, 8.45 MB)
Kimberlite, ultramafic and alkaline lamprophyres and other alkaline ultrabasic rocks occur within a broad belt that parallels the Rocky Mountain Trench. Most occur east of the trench, only a few are found west of it. They predate the JuraCretaceous Columbian Orogeny. Complexes in the Kechika River area, Ospika Pipe area, Golden-Columbia Ice fields area, Cross Kimberlite, Purcell breccia Pipes, and the Bull River area are discussed in paper.
