This paper reports the results of remapping the Mountain Grove pluton, situated in the Sharbot Lake domain in the central part of the Central Metasedimentary Belt, Grenville Province, Ontario. The pluton, previously mapped as a single body of gabbroic rock, is now described as comprising two distinct intrusions. The paper begins with an overview of its geologic setting, then describes the lithology of the two intrusion units, associated dykes, and neighbouring intrusions & plutons. The geochronology of the pluton and its mineral deposits are also briefly noted.

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.

Presents a geochronological and geochemical study of the Barbers Lake and McLean plutons in the Grenville Province of Ontario, including comparisons of whole-rock analyses of these plutons with the Elphin and Leggat Lake plutons. The assignment of various plutons in the study area to one of several age groups is 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 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.

Describes studies conducted as part of a program to provide baseline data of surficial materials, ice-flow history, and soil geochemistry in the Yellowknife area, aimed at augmenting the geoscience database to support mineral exploration & development. After description of the regional setting & bedrock geology of the area, information is presented on surficial sediments (till, glaciofluvial & glaciolacustrine sediments, peat), ice flow patterns, glacial history, and pebble lithology provenance.

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.

This study presents theoretical aspects and results of analyzes of the adsorbed water thicknesses and number of water molecular layers on pore surfaces for 11 sedimentary rock samples obtained from 850-950 metres depth in a Northwest Territories well. An additional purpose of the study was to determine if the adsorbed water content shows an increase with decreased temperature below 25 degrees C. Information is included on the analytical methodology. The results provide information that can be used to model the effect of temperature on the permeability history of compacting shale & mudstone under low temperature environments.
