This report provides a rationale and scientific basis for three multi-disciplinary research projects undertaken during the Smoking Hills fieldwork campaign of July, 2018 (Fig. 1.1).
It summarizes their field sample collections and observations and discusses their future research plans. The first activity concerns the age and environment of deposition of Cretaceous strata (145-66 Ma) in the Canadian Arctic mainland. This study
will provide new insights into the tectonostratigraphic evolution of the offshore Canada Basin and the regional Mackenzie-Beaufort and Sverdrup basins. This study is also expected to provide insight into Cretaceous climates of the Canadian Arctic.
The second activity concerns the study of bocannes, areas of burning shale/mudrock for which the Smoking Hills is aptly named. It aims to collect samples of minerals from within the burning vents and also to study the chemistry of ponds and streams
draining from these features and associated bedrock. The final activity is focused on kimberlite (diamond) indicator minerals and tries to draw comparisons between those found in deposits in the Smoking Hills with those previously recovered in
related deposits on Banks Island. This activity will also examine sediments from mapped areas of Neogene fluvial Beaufort Formation (<23-2.58 Ma), and from Quaternary glacial deposits (<2.58 Ma).
|Summary||(Plain Language Summary, not published)|
This Report of Activities presents the scientific rationale behind the Smoking Hills research project. It discusses the types of field investigations
undertaken by three sub-projects, and sample collections. Studies include Cretaceous stratigraphy and paleoenvironmental analysis, bocannes (burning shale) and related minerals and hydrochemistry, and Tertiary fluvial deposits and Quaternary glacial
history related to diamond indicator mineral dispersal.
