| Abstract | Occurrences of rocks, minerals and fossils are described from over one hundred and fifty localities from Buckingham to Mont-Laurier, St-Jovite and Grenville in Quebec, and in Ontario between Hawkesbury
and Ottawa. These occurrences provide a variety of specimens including some potential ornamental types such as feldspar, serpentine, marble, and granite.
Probably the best known area is the du Livre River valley where the intense mining activity
that began nearly a century ago has left numerous former apatite, mica, feldspar and graphite mines. Their dumps still furnish the collector with good specimens of the ore minerals as well as a variety of accessory minerals. Other deposits in the
region yield specimens of hematite, asbestos, barite, galena, etc.
In the region between Mont-Laurier, St-Jovite and Grenville, dumps of old mines and quarries contain specimens of ilmenite, graphite, garnet, serpentine, kaolinite, marble,
granite, etc. Only the serpentine and marble occur in specimens sufficiently large to be used for lapidary purposes.
Ordovician limestones containing some fossils are exposed along the highway, the shoreline, and in quarries between Hawkesbury
and Ottawa. These rocks are not rich in minerals except for calcite. |
