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 The analytical data were extracted from a large, mostly unpublished data set that includes uranium/lead, potassium/argon, and argon/argon geochronometry for other parts of the Anahim Lake and Mount Waddington map areas.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.

Geological Survey of Canada, Current Research (Online) no. 2005-A2 available in PDF, EPUB and Kindle. The West Tuya lava field is located about 95 kilometres north-north-west of Dease Lake, British Columbia. This report presents an overview & summary of field work, geographic information system spatial analysis, and preliminary petrographic analysis conducted at the field in 2003-04. Highlights of this work include: identification of three sub-aerial shield volcanoes and their mineral composition; confirmation that mantle-derived peridotite inclusions are present at two of the volcanoes; and interpretation of the sub-aerial lava flows. The minimum and maximum volumes of material erupted are also estimated.

Geological Survey of Canada, Current Research (Online) no. 2004-F1 available in PDF, EPUB and Kindle. This paper presents results from uranium-lead dating of plutonic, volcanic, & sedimentary rocks from the Southern Indian Lake to Granville Lake area of northern Manitoba. The samples analyzed were collected from a range of tectonostratigraphic settings and provide constraints on the age of volcanism & sedimentation in the Rusty Lake Belt, on the deposition of fluvial to littoral facies sediments in the Partridge Breast Belt, and on the emplacement of orthogneiss and plutonic rocks.

Geological Survey of Canada, Current Research (Online) no. 2004-C7 available in PDF, EPUB and Kindle. This report presents findings of a bedrock geological mapping project carried out in 2003 in the Ferguson Lake area, located about 200 kilometres west of Rankin Inlet, Nunavut. The project was initiated to provide better understanding of the geology & deformation history of the area and to put a local nickel-copper-platinum group element deposit into a regional context. The main part of the report describes the rock units exposed in the area (metamorphosed supracrustal rocks and intrusive rocks) and the area's structural elements (gneissosity, folds, foliation, shear zones, faulting). An attempt is then made to correlate the deformational features observed in the area with those documented by other researchers. Finally, implications of the findings for the timing of mineralization are briefly discussed.
