Lafarge Montréal-Est quarry (Carrière Lafarge Montréal-Est; Francon Montréal-Est quarry), Montréal, Québec, Canada

StandardDetailedBy ChemistryMapsSearch Google

Huge operating (1980-2007) limestone quarry (Lafarge Co.) within the city of Montréal in the old Montréal-Est district. The limestone is intruded by an enormous igneous dyke up to 5 m thick which is exposed for a length of over 1 km in the quarry. There are also alkaline sills probably related to the Monteregian alkaline province (Mont St-Hilaire etc.). The minerals occur mostly in tiny cavities in the sills.
