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.

This report outlines preliminary field results of bedrock mapping of a central Baffin Island study area that straddles the eastern segment of the Trans-Hudson Orogen. Orthogneiss in the Archean basement and rocks of the Paleoproterozoic Piling Group are described from the lowest to highest structural levels (Dewar Lakes, Flint Lake, Astarte River, Bravo Lake, Longstaff Bluff and related formations, the Cumberland Batholith, and the diabase dikes of the Franklin swarm). The final sections discuss deformation & metamorphism in the study area and briefly assess the potential for mineral deposits.

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.
