BOOK EXCERPT:

The Hazen Formation is an especially significant unit in northern Ellesmere Island and Greenland, as its depositional history spans the Cambrian to Silurian and underlies (and is exposed) throughout a substantial portion of the Arctic Islands. Four of its subdivisions can be mapped individually and correlated over at least 100 kilometres. This paper provides preliminary observations concerning the nature and correlation of the Hazen Formation with age-equivalent portions of the basinal succession in northern Greenland and the adjacent shelf succession of north-east Ellesmere Island. The paper describes the stratigraphy of the outer- shelf and basin-fill successions exposed on Judge Daly Promontory, the five mapped subdivisions of the Hazen Formation, and the age & correlations of the Formation.

BOOK EXCERPT:

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 EXCERPT:

The Upper Triassic sections outcropping on the Queen Charlotte Islands contain outstanding successions of conodont and radiolarian microfossils. This report focuses on the successions about the Carnian-Norian boundary at several key localities. This boundary may coincide with an interval of significant change in global fauna and flora, particularly in terrestrial habitats. The purpose of the study reported is to demonstrate faunal change that may potentially be used in global correlation and definition of the Carnian-Norian boundary, and thus contribute towards the resolution of historical events that date from that time. The report summarizes the radiolarian change within the boundary interval identified primarily by conodonts but supplemented by some molluscan data.

BOOK EXCERPT:

This research tested the feasibility of using existing information from regional bedrock & surface mapping and local water well records to map aquifers and interpret potential groundwater resources in the Vanderhoof area of central British Columbia. Information is included on local geology & stratigraphy, groundwater levels & flow, and water quality. The results provide understanding of the hydrogeological systems at work in the study area in general terms.

BOOK EXCERPT:

Reports research conducted in the Vernon area of southern interior British Columbia to search out and map marker units in high-grade Neoproterozoic and Palaeozoic metamorphic rocks, and to map the east-west extent of overlying Triassic Slocan Group strata. Stratigraphic relations in the area are summarized and detailed stratigraphy of a calcareous quartzite marker unit is described. Regional correlations of this marker unit with map units farther east & north and elsewhere in the Vernon map area are then discussed. The paper examines the hypothesis that the marker unit is the same succession that hosts the Kingfisher and Big Ledge lead-zinc occurrences, with implications for the exploration potential for base metals in the study area.

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.
