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.

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 The analytical data were extracted from a large, mostly unpublished data set that includes uranium/lead, potassium/argon, and argon/argon geochronometry for other parts of the Anahim Lake and Mount Waddington map areas.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