This book was released on 2004 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: The area studied in this paper covers southern Cortes Island, Marina Island, and north-west Hernando Island in the Strait of Georgia, British Columbia. The paper first reviews the geological setting & physiography of the study area, then presents results of mapping Pleistocene (Wisconsinan) strata exposed in the area. The stratigraphic succession, having maximum thickness of 130 metres, is subdivided into six major units, all recording cyclical, climate-controlled, primarily marine deposition. Established names are used for two widespread formations (Cowichan Head and Quadra Sand) and local names are introduced for newly determined formations. Probable sources of the formation sediments are briefly discussed.

This book was released on 2004 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report details the results of geochronological measurements made on 19 samples from locations in & directly adjacent to the eastern Bella Coola map area of British Columbia. The analytical data were extracted from a large, mostly unpublished data set that includes uranium/lead, potassium/argon, and argon/argon geochronometry for other parts of the Anahim Lake and Mount Waddington map areas. Analytical data, geological ages, and relevant observations for each dated sample are presented in chronological order. The age results provide broad constraints on pluton emplacement, volcanic eruption, and structural & metamorphic relationships in the study area, although these are discussed only in general terms.

This book was released on 2005 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Quilchena fossil site in the Okanagan Highlands of south central British Columbia is a rich repository of Eocene plant, insect, & fish fossils. Reliable age assignment of this site is critical in order to reconstruct the biogeographic, climatic, & evolutionary relationships between the flora & fauna of the Okanagan Highlands and those of other Tertiary sites around the world. Previous radiometric age determinations have been variable and inconclusive. This paper presents new data using uranium-lead dating of zircons from a thick tephra combined with argon-argon dating of sanidine crystals from the same bed. The age determined can be securely ascribed to the Quilchena fossils, since the dated tephra was deposited within the fossil-bearing shale & mudstone sequences.
