BOOK EXCERPT:
A distinctive group of giant quartz veins characterizes the Great Bear magmatic zone east of Great Bear Lake, Northwest Territories. They are topographically conspicuous, have attracted attention from mineral prospectors, and contain occurrences of uranium, copper sulphides, and other minerals. This paper presents results of the first study of fluid inclusions from giant quartz veins in this zone. Samples were studied from the Crowfoot and Ted uranium occurrences. It begins with descriptions of the regional geological setting, the quartz veins and associated stockworks, and the two occurrences studied. It then describes the fluid inclusion study methodology, petrographic observations, and temperature & salinity determinations of the fluid inclusion samples. The results are discussed with respect to the multi-stage developmental history of the quartz veins.

BOOK EXCERPT:
The purpose of this paper is to document results of the determination of electrical resistivity characteristics of schist samples from the Gold Lake area of the Yellowknife mining district, Northwest Territories, for use in interpreting ground electromagnetic surveys that have been conducted in that region. Results are presented from investigations of electrical conductivity mechanisms determined for five sub-samples taken from two mineralized schist samples selected to characterize the resistivity of the alteration zone and to determine the effect of cross-cutting veins & of fine-grained sulphide minerals oriented parallel to foliation. Resistivity-related factors examined in the study include sulphide grain connectivity, the insulating quality of quartz & calcite grain layers, and pore-fluid connectivity.

BOOK EXCERPT:
Presents an examination of field relationships along the northern margin of Baker Lake Basin, Nunavut, with the goal of establishing the stratigraphy of the Dubawnt Supergroup in relation to paleogeography, depositional setting, and provenance. Includes information on the regional geology, local geology (Christopher Island Formation sedimentary & volcanic rocks, the newly named Amarook Formation, and the overlying Pitz and Thelon formations), and discusses faulting during the development of the Baker Lake Basin.

BOOK EXCERPT:
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.
