Roches et minéraux du collectionneur : d'Ottawa à North Bay et Huntsville (Ontario); de Gatineau (Hull) à Waltham et Témiscaming (Québec)

Occurrences of minerals, rocks, and fossils are described from about 200 easily accessible localities on either side of the Ottawa River from Ottawa–Gatineau (Hull) to North Bay. They are reached by following Highway 17 in Ontario and Highway 148 in Quebec. Most of the collecting localities are in Renfrew County, Ontario. A wide variety of minerals are found in this area, and some localities are known for the museum-type specimens collected from them. The earliest mines were the apatite and iron mines that were operated in the 1880s. Other deposits were subsequently worked for corundum, molybdenite, zinc, celestine, garnet, pyrite, beryl, marble, limestone, feldspar, rare-element minerals, and dolomite. Numerous former feldspar mines as well as deposits of kyanite, garnet, muscovite, niobium, and brucite occur in the Nipissing District. Some of these deposits are accessible only by boat. The region north of the Ottawa River between Gatineau (Hull) and Waltham was formerly mined for iron, mica, feldspar, apatite, uranium, molybdenum, lead-zinc, and limestone. A dolomite deposit is currently (2005) being operated. Occurrences of brucite, pyroaurite, szaibelyite, cordierite, scapolite, and asbestos are also known. Farther west, in the
