Book Description
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.

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
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.

Book Description
The Nicola Horst in the southern intermontane belt, British Columbia, is a Tertiary fault-bounded structure that exposes relatively deep-seated metamorphic equivalents of Late Triassic Nicola Group volcanic & sedimentary rocks, intruded by plutons. Associated with the Nicola facies are undated conglomerate & schist units which are unlike any known facies of the Nicola Group but which resemble units of the pre-Nicola, pericratonic succession to the east. This paper presents preliminary results of field work conducted to better understand the evolution & contact relationships of the Nicola Horst and to examine whether the Horst provides evidence regarding the contact between the Nicola Group and the ancient North American cratonic rocks.

Book Description
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.

Book Description
Cambrian to Mississippian metasedimentary and metavolcanic rocks of the Eagle Bay Assemblage in the Adams Lake area of south central interior British Columbia host numerous polymetallic sulphide deposits. This paper describes the Samatosum and Rea massive sulphide deposits located in that area, their geological settings, structure, metamorphism, and mineralization. Some fundamental structural & stratigraphic problems in the region are addressed, and implications for understanding the genesis of the sulphide mineralization are discussed.
