Geology Of Graham Island British Columbia

"During the course of the present detailed stratigraphic studies careful attention was paid to occurrences of bitumen, dead oil, fetid lithologies, and possible porous intervals within the Jurassic rocks. Hydrocarbons, derived from normal petroleum type hydrocarbons, were noted throughout the lower and middle Jurassic. The present evidence suggests that hydrocarbon reserves may be encountered in the subsurface in northern Graham Island, southern Hecate Strait, and Queen Charlotte Sound. These potential resources involve mesozoic oil within the Jurassic or Cretaceous rocks, or escape oil of Mesozoic age in Tertiary sandstone units." --

This book tells the story of the province's geology and the history of its living creatures. The first edition of Geology of British Columbia, with its accessible but rigorous science, struck a chord with readers. Since it was first published, theories about plate tectonics and the geological history of British Columbia have evolved, and this new edition reflects the current thinking. This book also features updated content throughout, seven new maps, and a number of new photographs. A brand new appendix lists and describes key geological sites in British Columbia, adding a field-guide compon.
