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.

This report details the results of geochronological measurements made on 19 samples from locations in & directly adjacent to the eastern Bella Coola map area of British Columbia. The analytical data were extracted from a large, mostly unpublished data set that includes uranium/lead, potassium/argon, and argon/argon geochronometry for other parts of the Anahim Lake and Mount Waddington map areas. Analytical data, geological ages, and relevant observations for each dated sample are presented in chronological order. The age results provide broad constraints on pluton emplacement, volcanic eruption, and structural & metamorphic relationships in the study area, although these are discussed only in general terms.
