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
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
This research focuses on the possibility of a coastal migration and/or colonization route via the Queen Charlotte Islands during the period 15,000-8,500 years before present. It assesses two aspects of the changing environment in the Islands during this period: sea level change and available edible biomass for early human populations. Potential food sources of an early coastal migrating population would likely include intertidal edible molluscs. The research examines high-stand deposit locations ranging from 1 to 18 metres above sea level for evidence of edible mollusc shells. Dating of the samples collected will provide a record of high-stand elevations across the Islands, thereby providing a data set with which to model isostatic sea level response on the British Columbia continental margin.

Book Description
Komatiite units dominate Archean volcanic successions in the Laughland Lake and Walker Lake map areas of the Committee Bay region, central Nunavut. This study describes results of regional & local mapping of some well-preserved komatiite sequences in those areas, particularly in the Laughland Lake area where the majority of the better-preserved komatiite units are found. Structural & stratigraphic relationships are also discussed.

Book Description
This report describes sand dykes, extensional faulting, and complex deformation of strata as observed in the Kirkpatrick sand & gravel pit located at the north margin of the Fraser Lowland near Maple Ridge, British Columbia. The pit is excavated in a prominent bench of glacial sediments which exposes part of a delta constructed during deglaciation. The report describes the stratigraphic evidence bearing on the origin of the sand dykes and deformation, and discusses possible triggering mechanisms including non-seismic landsliding and earthquake ground shaking.

Book Description
This paper examines a small area west of Verrill Canyon on the Scotian Slope to address whether sedimentological and geomechanical features of piston cores would explain the localized occurrence of sediment failures. The seabed in the area was divided into zones of disturbed, undisturbed, and erosional areas, and six continuous acoustic reflectors were traced throughout the area from high-resolution acoustic records. Nine sediment cores, providing a composite stratigraphy of the acoustic section, are described and the relationship of the failure horizons to core lithology and physical properties is discussed.
