Book Description
This study examines aspects of the geological evolution of the Sharbot Lake domain and compares it with that of neighbouring domains & terranes in the Central metasedimentary belt, Grenville Province, Ontario. The study reports uranium-lead zircon & titanite geochronological ages for a granodiorite phase of the Pakenham intrusion from the northern part of the Sharbot Lake domain. The new data expand the known range of magmatism in this part of the belt, elucidate the early tectonic evolution of the domain, and constrain the timing of overprinting metamorphism. Possible links between the Pakenham structure and the Wolf Grove structure to the south-east are also discussed.
