 Ste-Justine – Cavité de calcite, quartz, et chalcopyrite
Minerals from the Beekmantown Dolostones Of Quebec and Ontario
The dolomitic limestones or dolostones of the Beekmantown Group of Lower Ordovician age are prolific source of crystallized minerals, especially Dolomite, Calcite and Quartz.
The presence of cavities lined with crystals was reported as early as 1863 by Sir William Logan in his Geology of Canada.
In Quebec, the Beekmantown loclities Group is represented by the Beauharnois Formation which is exposed in a number of quarries around the Island of Montreal.
Most known among this are Marcil quarry near Ste-Clotilde-de-Châteauguay, Mathers quarry in St-Eustache, Trudeau quarry in St-Justine-de-Newton and Meloche quarry near Salabery-de-Valleyfield
In the Ottawa area of Ontario the Beekmantown Group is represented by the Oxford Formation. Most known localities suach as Blair farm outcrop and Grant quarry near Greeley famous for the Smoky hopper Quartz
Cavities producing collector-quality specimens are generally restricted to single horizons no more than 2 meters in thickness.
Some cavities are up to 2 meters across and several meters deep.
Associated with Dolomite, Calcite and Quartz are: Pyrite, Baryte, Sphalerite, Galena, Chalcopyrite, Nacrite, Anatase and Gypsum.
These minerals occur more sparingly, and as much smaller crystals.
