Five breccias occur in the Carboniferous rocks of The Billefjorden area of West Spitsbergen. Evidence poins to the origin of some of the breccia beds as due to collapse following solution in underlying strata; others are yet to be explained. It is certain, however, that none of the breccias originated under unstable depositional conditions.
