Flat, disc-shaped calcareous concretions are found in unconsolidated Pleistocene fine sand and silt of glaciolacustrine origin in Laurentides Park, north of Quebec City, Canada. About 40% of the concretions are faulted, the faults passing into surrounding sands. it is suggested that faulting took place in frozen sediments (ground temperature close to 0°C), and that cementation also occurred after displacement.
