Architectural dolomite quarrying in Québec

Dolomite has been quarried in a few locations in southern Québec. The dolomite has mainly been used as foundation stone (rubble stone).

Ordovician dolomites from the Beauharnois Formation of the Beekmantown Group have been used to build churches and houses (Jacob and Ledoux, 2003, p. 10). The stone was hard and brittle, which made it difficult to dimension and limited its use. Clark (1972, p. 212-213) found it surprising that this dolomite had not been used as building stone on a larger scale. Even though it takes on a buff colour when altered, this nearly pure dolomite which contains little quartz is still a quality stone.

In Québec, exploitation work has been recorded in the following thirteen areas, which are classified in alphabetic order of location regardless of the importance of the extracted stone volume. To obtain more geological and factual data, click on the corresponding link for each location.
