This book was released on 2004 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents results of geological mapping conducted in 2003 as part of a project addressing the stratigraphic, structural, and metamorphic relationships along the Columbia River valley in British Columbia. The results relate to the stratigraphy of the Upper Arrow Lake & Trout Lake areas and the structural geology of the Columbia River fault zone. The significance of the stratigraphic succession found along Upper Arrow Lake is discussed in regard to previous theories concerning a crustal-scale displacement along the fault zone.

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 The analytical data were extracted from a large, mostly unpublished data set that includes uranium/lead, potassium/argon, and argon/argon geochronometry for other parts of the Anahim Lake and Mount Waddington map areas.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 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was conducted in response to concerns raised by local residents about water quality in Fisherman Lake, located 18 kilometres north-west of Fort Liard, Northwest Territories. Field investigation of the lake revealed the existence of 13 gas seeps (largely methane) with distinct bubble trains rising continuously to the surface. This paper presents results of analyses of the gas & of the lake water and the determination, through isotope analyses, of whether the gas is of biogenic origin (related to the decomposition of organic matter) or thermogenic origin (representing a seep from geological strata of the gas field below the lake). The possible effects of methane on the lake water are also discussed and recommendations are made for further research.
