Abstract
The Rural Municipality of Ste. Rose was mapped this year as part of an ongoing project to update aggregate information in the province. The last study of this rural municipality was completed in 1978. The aggregate resources are contained in beach ridges formed by glacial Lake Agassiz. There are two major beach complexes: the Ste. Amelie ridge, which has been a long-standing source of aggregate, and a second ridge along the eastern boundary of the municipality which, due to inaccessibility, has only one pit. The material in the complexes ranges from sandy coarse pebble gravel to fine sand. The gravel is of very high quality, with a pebble lithology averaging 75% carbonate and 25% Precambrian clasts and a good range of grain sizes. There is no shale in the aggregate and the only deleterious material was some carbonate cementation. While many of the pits in the Ste. Amelie ridge are near depletion, it still contains large reserves of aggregate. The eastern deposits will become more important as the Ste. Amelie ridge becomes depleted.
