APPENDIX? PEACE RIVER CANYON COAL AREA DETAILS OF COLUMNAR SECTIONS? “Thick” refers in general to layers over 6 inches thick; thin to those under 6 inches. ‘‘Shale” refers to fine-grained argillaceous beds, having the structure of shale, i.e., breaking in layers that have curved surfaces; these layers further break down into irregular and angular fragments. “Fissile shales’? as so designated here are those that break into smooth sheets or plates parallel to bedding. “Flag”, ‘“‘flaggy,” and ‘“‘flagstone”’ refer to the nature of the bedding and not to the grain and composition of the rock; the rock weathers into layers parallel to the bedding, each layer being a natural stratum.
