Book excerpt: 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 book was released on 2000 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: 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.

This book was released on 2000 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2000 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2000 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study used major & trace-element geochemistry to characterize the granitoid rocks of the Shikag-Garden lakes area of northern Ontario and to examine their petrogenesis & tectonic setting. Neodymium isotopes were examined to examine crustal recycling and to estimate the age of crustal sources contributing to the granitoid rocks. The data are subsequently interpreted to shed light on the distribution of basement terranes in the central Wabigoon Subprovince.

Book excerpt: 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.

This book was released on 2000 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insight into the Archean thermal & tectonic regime may be offered by studying the late Archean Quetico alkaline province, a suite of carbonate-bearing magmatic complexes associated with a recently discovered carbonatite body in north-west Ontario. This paper attempts to give a broad overview of the character of several such bodies examined in the Quetico alkaline province in summer 1999. It first describes the general geology of the study area and the chemical compositions of the intrusions studied. It then describes the field characteristics of the North Elbow Lake, Whalen lake, Harnett Lake, and Beaverhouse Lake intrusions. Origin of the intrusions is also discussed.
