Book excerpt: 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.

This book was released on 2000 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Slave Province is a relatively small but well-exposed Archean craton in the north-west part of the Canadian Shield. Mapping of quartzite & banded iron formation occurrences throughout the Province since the 1970s has resulted in the conclusion that the overall topology of all greenstone belts in the central & western parts of the Province permits all such occurrences to be correlated into a single cover sequence, the Central Slave Cover Group. Following a brief historical overview, this paper presents field evidence for the discovery & successful correlation of that cover sequence across much of the craton. It then presents detrital zircon data to bolster this correlation, in particular to show that what was earlier mapped as a Paleoproterozoic cover sequence in central Wopmay Orogen is in fact part of the Central Slave Cover Group. The extension of the Cover Group into the north-western Slave Province have implications for the architecture & evolution of continental crust older than 2.85 billion years.

This book was released on 2005 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents results from a Quaternary mapping project conducted in two areas of central mainland Nunavut that were located beneath the Keewatin Ice Divide during the last glaciation. Field work included surficial mapping, regional-scale till sampling, stratigraphic studies, and ice-flow indicator surveys. The paper summarizes the findings related to ice flow directions, patterns, and the sequence of flow events in the two map areas. Preliminary interpretations are offered of the ice flow record from the oldest recognized ice-flow events to the most recent flows.

This book was released on 2000 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study examines aspects of the geological evolution of the Sharbot Lake domain and compares it with that of neighbouring domains & terranes in the Central metasedimentary belt, Grenville Province, Ontario. The study reports uranium-lead zircon & titanite geochronological ages for a granodiorite phase of the Pakenham intrusion from the northern part of the Sharbot Lake domain. The new data expand the known range of magmatism in this part of the belt, elucidate the early tectonic evolution of the domain, and constrain the timing of overprinting metamorphism. Possible links between the Pakenham structure and the Wolf Grove structure to the south-east are also discussed.

This book was released on 2004 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents results from uranium-lead dating of plutonic, volcanic, & sedimentary rocks from the Southern Indian Lake to Granville Lake area of northern Manitoba. The samples analyzed were collected from a range of tectonostratigraphic settings and provide constraints on the age of volcanism & sedimentation in the Rusty Lake Belt, on the deposition of fluvial to littoral facies sediments in the Partridge Breast Belt, and on the emplacement of orthogneiss and plutonic rocks.

This book was released on 2000 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report analyzes airborne gamma spectrometric data acquired over the Endako porphyry district in British Columbia in 1995, along with surface & lithogeochemical data, to assess their utility as an aid to geological mapping and mineral exploration. It begins with background on the geological setting, including surficial & bedrock geology. Results of analyses are then presented with regard to correlations between airborne & surficial mapping measurements, and the effects of various surficial features on measured airborne radioelement concentrations.

This book was released on 2000 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2000 with total page 13 pages. Available in PDF, EPUB and Kindle. 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.
