Plutonic rocks of the Canadian Shield are being assessed as a potential host medium for the storage of radioactive waste. A study of the geological framework of three structural provinces (Superior, Southern, and grenville) within Ontario has resulted in an inventory of 1365 plutons which are identified on Map 1533A at a scale of 1:1,000,000. The plutons have been classified by rock type: granite (sensu lato) comprises 75% of the plutons, gabbro 15%, alkalic rocks 8%, and anorthosite 2%.

The Funger lake Area covers approximately 386 square km in the District ofThunder Bay. The centre of the map area is about 30 km northwest of the townof Armstrong. The map area includes Early Precambrian (Archean) rocks of thevolcanic-plutonic Wabigoon subprovince of the Superior Province and lesserLate Precambrian (Proterozoic) rocks of the Nipigon Plate of the SouthernProvince.

Presents geochronological age determinations of zircons from eight plutons in the Grenville Province, Ontario (Oso and Mountain Grove plutons in the Sharbot Lake domain; Silver Lake & Bennett Bay plutons and Fall River mangeritic augen gneiss associated with the Maberly shear zone; North Crosby & Pike Lake plutons in the north-west sheared part of the Frontenac terrane; and the Beales Mills pluton in the interior of the Frontenac terrane). The results are used to propose a re-interpretation of the tectonics of the Frontenac suite and the origin of the magmas responsible.
