An oxygen isotope study of the Loon Lake pluton and the Apsley gneiss, Ontario
Abstract
The Loon Lake pluton in the Grenville province of Southeastern Ontario consists of a quartz monzonite rim surrounding a monzonite core containing inclusions of gneiss, gabbro and diorite. The pluton was emplaced in amphibolite facies Apsley gneiss, amphibolite and marble. Abnormally high δ18O values are observed in all igneous rock types: quartz monzonite (8.9–13.9‰), monzonite (8.9–9.7‰), diorite-gabbro (8.0–9.3‰). High 18O contents are …
