The Boundary Project was initiated in 2005 with the purpose of better characterizing the lithological and geochemical variations within and between the various Paleozoic sequences in the southern Okanagan region along the USA border. These occur within Quesnel terrane, which is dominated by Paleozoic mafic volcanic and pelitic rocks, unconformably overlain by Triassic and Jurassic volcanics and sediments, and intruded by various suites of Triassic, Jurassic and Eocene granitic rocks.
The results of isotopic dating and lithogeochemical studies of several of the granitic intrusions in the study area are presented in Massey et al. (2010). This geofile complements that paper and presents the full analytical data tables for samples analysed by both laser-ablation ICP-MS on zircons and Ar40/Ar39 on hornblende and biotite separates.
