Book Description
The North Caribou terrane is one of the largest blocks with continental affinities in the western Superior Province. This paper reviews field relationships at the southern margin of this terrane in the western Uchi belt between Trout Lake, north-west Ontario, and Lake Winnipeg, Manitoba. After an introduction on the regional geological framework, the paper describes the Trout Lake Batholith, the Red Lake-Garner Lake lobe, the Bloodvein-Wanipigow River corridor, the English Lake magmatic complex, and the eastern Lake Winnipeg area. Implications of the observations for crustal architecture are discussed.

Book Description
A well-exposed section about 250 metres wide below the high water line of the Jennings River, Teslin Lake map area in northern British Columbia shows part of the Teslin Fault and provides an opportunity to constrain the fault's kinematic history by direct ground observations. This report describes preliminary structural observations of this section of the Teslin Fault, including the rock types involved, mylonitic & ultramylonitic structures, and deformation. Indications of two main episodes of shearing are discussed.

Book Description
This report summarizes observations & structural data collected in the area of the Walker Lake shear zone in the Committee Bay supracrustal belt, central Nunavut. It first reviews the general geology of the metasedimentary & volcanic rocks of the Prince Albert group and the intrusive rocks (tonalite, granite) which were observed in the shear zone. It then describes the three generations of ductile structures that were identified in proximity to the shear zone, and offers some preliminary interpretations regarding the relationship of the shear zone to regional deformation.

Book Description
The use of static global positioning system (GPS) equipment for accurate horizontal & vertical positioning in field geology operations at high latitudes is made difficult by the need to set up & operate a GPS reference station and limitations on the distance between the reference station & field GPS due to errors introduced by the ionosphere. Dual-frequency GPS receivers have the potential to eliminate these problems since they can eliminate ionospheric errors and thereby increase baseline lengths, thus potentially permitting the use of existing GPS reference stations. This paper describes the use of a dual-frequency receiver for establishing benchmarks along the Yukon River as a field trial of this technology. Field methods and post-processing of the data using GPS data from permanent receiving stations are described, and baseline results are presented. The derived benchmarks will be applied to a survey of fill thickness below the Yukon River.

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
Describes uranium-lead dating of zircon and titanite from two representative samples of two plutons (diorite and quartz monzonite) in the Tetachuck Lake map area of central interior British Columbia. Includes information on the geological nature & setting of the sampled plutons, analytical procedures, and geochronology. The correlation of the two plutons with the metallogenically important group of Late Cretaceous Bulkley plutonic suite is discussed.
