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 The analytical data were extracted from a large, mostly unpublished data set that includes uranium/lead, potassium/argon, and argon/argon geochronometry for other parts of the Anahim Lake and Mount Waddington map areas.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

Book Description
The Goldcorp high grade zone at the Red Lake mine in northern Ontario is currently the best Canadian example of high-grade gold mineralization. It provides an opportunity to define the fundamental geological parameters controlling the formation of high-grade gold ore and to assist in developing exploration guidelines for such mineralization. This report updates an ongoing study of the Red Lake high grade zone, beginning with a review of the local geological setting and a description of the southeast-trending structural lineament known as the Red Lake mine trend, defined by folds, faults, and an associated corridor of alteration & mineralization. The report then describes the structure, veins, ore zones, and alteration assemblages in the high grade zone and discusses the chronology of gold replacement, gold remobilization, and the geological controls on formation of the high grade zone.

Book Description
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.

Book Description
Formation resistivity factor and pore-surface resistivity values were determined for three mineralized & nonmineralized rock samples from the Giant mine & Con mine areas of the Yellowknife mining district. The purpose was to provide basic information required to understand the electrical conductivity mechanisms of these rocks and to aid interpretation of geophysical surveys conducted in these areas. This paper describes the methods & processes used to obtain the formation factor data & to document the results for use in future studies.
