Book Description

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.

Book Description

The Samuels Lake intrusion is an elliptical body about 600 by 300 metres located about halfway between Atikokan and Rainy Lake in north-west Ontario. The intrusion is similar to an array of mafic-ultramafic intrusions east of Atikokan called the Quetico Intrusions, and contains platinum group element (PGE) mineralization associated with the occurrence of sulphides, especially chalcopyrite. This report describes the lithology of the four distinct igneous phases of the intrusion, its structure, and its sulphide & PGE mineralization. Similarities with & differences between the Quetico Intrusions are noted.

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.




Laboratory Manual for Introductory Geology


Book Description

Developed by three experts to coincide with geology lab kits, this laboratory manual provides a clear and cohesive introduction to the field of geology. Introductory Geology is designed to ease new students into the often complex topics of physical geology and the study of our planet and its makeup. This text introduces readers to the various uses of the scientific method in geological terms. Readers will encounter a comprehensive yet straightforward style and flow as they journey through this text. They will understand the various spheres of geology and begin to master geological outcomes which derive from a growing knowledge of the tools and subjects which this text covers in great detail.
