Book Description
The area studied in this paper covers southern Cortes Island, Marina Island, and north-west Hernando Island in the Strait of Georgia, British Columbia. The paper first reviews the geological setting & physiography of the study area, then presents results of mapping Pleistocene (Wisconsinan) strata exposed in the area. The stratigraphic succession, having maximum thickness of 130 metres, is subdivided into six major units, all recording cyclical, climate-controlled, primarily marine deposition. Established names are used for two widespread formations (Cowichan Head and Quadra Sand) and local names are introduced for newly determined formations. Probable sources of the formation sediments are briefly discussed.

Book Description
The North Caribou terrane is one of the largest blocks with continental affinities in the western Superior Province. This paper reviews field relationships at the southern margin of this terrane in the western Uchi belt between Trout Lake, north-west Ontario, and Lake Winnipeg, Manitoba. After an introduction on the regional geological framework, the paper describes the Trout Lake Batholith, the Red Lake-Garner Lake lobe, the Bloodvein-Wanipigow River corridor, the English Lake magmatic complex, and the eastern Lake Winnipeg area. Implications of the observations for crustal architecture are discussed.

Book Description
Presents results of 1999 field studies focusing on the structure & stratigraphy within the Wallace Lake greenstone belt of east central Manitoba. The stratigraphic results involve redefinition of some of the sequences previously described in the belt and the introduction of new stratigraphic nomenclature. The nature of the contact between stratigraphic assemblages, and the internal stratigraphy of these assemblages, is then presented. This is followed by a discussion of the stratigraphic position of various komatiitic units found in the belt. The final sections describe the geochemistry of the volcanic rocks and the structural history of the greenstone belt.

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.
