Book Description
This report analyzes airborne gamma spectrometric data acquired over the Endako porphyry district in British Columbia in 1995, along with surface & lithogeochemical data, to assess their utility as an aid to geological mapping and mineral exploration. It begins with background on the geological setting, including surficial & bedrock geology. Results of analyses are then presented with regard to correlations between airborne & surficial mapping measurements, and the effects of various surficial features on measured airborne radioelement concentrations.

Book Description
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 Description
The Upper Triassic sections outcropping on the Queen Charlotte Islands contain outstanding successions of conodont and radiolarian microfossils. This report focuses on the successions about the Carnian-Norian boundary at several key localities. This boundary may coincide with an interval of significant change in global fauna and flora, particularly in terrestrial habitats. The purpose of the study reported is to demonstrate faunal change that may potentially be used in global correlation and definition of the Carnian-Norian boundary, and thus contribute towards the resolution of historical events that date from that time. The report summarizes the radiolarian change within the boundary interval identified primarily by conodonts but supplemented by some molluscan data.

Book Description
This study examines aspects of the geological evolution of the Sharbot Lake domain and compares it with that of neighbouring domains & terranes in the Central metasedimentary belt, Grenville Province, Ontario. The study reports uranium-lead zircon & titanite geochronological ages for a granodiorite phase of the Pakenham intrusion from the northern part of the Sharbot Lake domain. The new data expand the known range of magmatism in this part of the belt, elucidate the early tectonic evolution of the domain, and constrain the timing of overprinting metamorphism. Possible links between the Pakenham structure and the Wolf Grove structure to the south-east are also discussed.

Book Description
This research tested the feasibility of using existing information from regional bedrock & surface mapping and local water well records to map aquifers and interpret potential groundwater resources in the Vanderhoof area of central British Columbia. Information is included on local geology & stratigraphy, groundwater levels & flow, and water quality. The results provide understanding of the hydrogeological systems at work in the study area in general terms.

Book Description
The final year of the Nechako NATMAP project to study the geology of central British Columbia was used to research information collected in the field & laboratory, and to compile & document the study results. This article includes a review of upcoming publications & other products, by type of product: maps, journal articles, conference presentations, and computer products, as well as ongoing research on petrology, palaeontology, terrane characterization, tectonics & structure, and Quaternary geology.

Book Description
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 Description
Presents geochronological age determinations of zircons from eight plutons in the Grenville Province, Ontario (Oso and Mountain Grove plutons in the Sharbot Lake domain; Silver Lake & Bennett Bay plutons and Fall River mangeritic augen gneiss associated with the Maberly shear zone; North Crosby & Pike Lake plutons in the north-west sheared part of the Frontenac terrane; and the Beales Mills pluton in the interior of the Frontenac terrane). The results are used to propose a re-interpretation of the tectonics of the Frontenac suite and the origin of the magmas responsible.
