Objective(s): To scope the Imperial Formation in order to develop a more extensive future study of this formation, and to sample the sites for conodont fossil bearing carbonates in order to better age date the Horn River Group deposits.

Project Description: The objective is to scope the Imperial Formation in order to develop a more extensive future study of this formation, and to sample the sites for conodont fossil bearing carbonates in order to better age date the Horn River Group deposits.

At each site the rock exposure will be photographed in detail. At Mountain River and Gayna Gorge the outcrop will be sampled for conodont fossil bearing carbonate rock.to the research team will take ~10 samples at each location. Each sample will be ~3 kg of rock. At the other sites ~10 samples, each weighing ~ 500 grams will be taken for geochemical analysis. The exact number of samples taken at each site will depend on the suitability of the rock for sampling and analysis.

The study will increase and enhance the knowledge of the region’s geological history, which will be made public through various methods to the communities, increasing their opportunity for informed decision making. Additionally, the increased knowledge of local resource potential might lead to future economic activity in the regions, leading to indirect, but related possible opportunities and involvement.

At the conclusion of this year's study, a short summary will be provided to the communities, describing the field work and findings in plain language. Detailed scientific reports will be published and available on the Northwest Territories Geological Survey website and presentations will be given annually at the Yellowknife Geoscience Forum. Additionally, at the conclusion of the main study (2022), the results will be presented locally in communities, as appropriate.

The fieldwork for this study will be conducted from July 23, 2019 to July 29, 2019.
