Project: Geochemical characterization of the Jurassic Bonanza arc and Tertiary intrusions on Vancouver Island.
Despite their economic significance in hosting known porphyry Cu-(Mo-Au) deposits and former mines, the Jurassic and Paleogene aged intrusions on Vancouver Island have received scant detailed study regarding their origin and emplacement. I will carry out isotopic characterization (Pb, Sr, Nd, O, S) to identify the source of the magmas and their related endowments in Cu, Mo or Au. This will aid in distinguishing suites of plutons that are suitable targets for exploration, and also shed light on the construction and evolution of continental crust. The first part of this project involves isotopic mapping of the intrusions of the Jurassic Bonanza arc, which form the substrate into which later Paleogene intrusions are emplaced.
