Notes
All isotopic dates are calculated using the decay constantsrecommended by Steiger and Jäger (1977); recent estimatesof K decay constants would increase the Ar/ Ar age byca. 1%.
Geology in remote areas and outside the limit of mapping wascompiled from BC Assessment Reports and Muller and Roddick(1983).
CIPW (wt %) normative compositions projected in QAP: Q (qz), A (Or) and P (Ab+An) taking Fe2O3 as 0.15FeOt (total Fe as FeO). Nomenclature of plutonicrocks on the map is based on the IUGS modal QAP mineralogical classification. Any discrepancy between modal and CIPW rock nomenclature is due inpart to the projection scheme. The CIPW projection of least altered plutonic rocks (n=107; grey/black dots) yields an overabundance of Or in the norm dueto the presence of K-bearing mafic hydrous minerals (biotite, hornblende) relative to the mesonorm (red crosses); the latter produces a bias towards tonalitein the granitoid rocks (not a common rock type) whereas the CIPW projection shows bias towards quartz monzodiorite (much less common than quartz diorite).
Acknowledgments
We sincerely appreciate the warm hospitality shown to us bythe residents of northern Vancouver Island. We thank MargaretHanuse and Dave Ross for accommodations in Port McNeilland Holberg, respectively. John Fleming, BHP-Utah Mines Ltd.,kindly granted access to maps, drill logs and core from the IslandCopper Mine and other properties. Western Forest Products Inc.provided maps and digital files of logging roads in the area.Critical reviews by L. J. Diakow, N. W. D. Massey, J. L. Nelsonand P. Schiarizza greatly improved the final cartographic product.Sadly, one of our co-authors, Dr. E. T. Tozer of the GeologicalSurvey of Canada, passed away recently; his contributions toinvertebrate palaeontology will be sorely missed.
