Basic friction angles of carbonate rocks from Kananaskis country, Canada

Basic friction angles of the Paleozoic carbonate rocks of Kananaskis Country, west of Calgary, Canada were determined on a tilting table to range from 21.5° to 41.3°. The basic friction angles of carbonate rocks with impurity contents under 10% increase with calcite content and grain size. Clay minerals reduce basic friction angles in carbonate rocks with impurity contents over 10%. Sliding angles from repeated tests decrease with displacements for dolostones but not for limestones. The friction angles of highly polished surfaces are 7.5 to 7.9° for dolostones and 11.8 to 13.0° for limestones, a difference attributed to the frictional properties of the minerals.
