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.

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.

Komatiite units dominate Archean volcanic successions in the Laughland Lake and Walker Lake map areas of the Committee Bay region, central Nunavut. This study describes results of regional & local mapping of some well-preserved komatiite sequences in those areas, particularly in the Laughland Lake area where the majority of the better-preserved komatiite units are found. Structural & stratigraphic relationships are also discussed.

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.

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.

Describes a geologic mapping project in the area of the Nechako reservoir in central interior British Columbia. Includes description of regional geology, stratigraphic units, volcanic & plutonic rocks, and geologic structure. Evidence for two periods of deformation of Hazelton Group rocks in the study area is discussed.
