Book Description

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%.

Book Description

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.
