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.

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.

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.

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.

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.
