Project Team: Dr Jan Peter (Supervisor - Mineral deposit studies, Geological Survey of Canada), Dr Dan Layton Matthews (Supervisor of PhD student and specialist in geochemistry, Queen's University), Dr. Paul Gammon (Supervisor - Surfical geology, Geological Survey of Canada), Dr. Andrew Conly (Supervisor - MSc student and ore deposit specialist, LakeHead University), Hendrik Falk (Mineral deposit researcher, Northwest Territories, Geoscience Office), Dr. Elizabeth Turner (Supervisor of MSc student, and specialist in stratigraphy, Laurentian University)

Objective(s): To identify proximal (close) and distal (at a distance) mineralogical and chemical elements that will indicate if rocks in a sedimentary basin are rich in metals; also, to understand how metals were emplaced in rocks and how they disperse as the rocks weather.

Project Description: The objectives of this research project are:
•to identify proximal (close) and distal (at a distance) mineralogical and chemical elements that will indicate if rocks in a sedimentary basin are rich in metals; and
•to understand how metals were emplaced in rocks, and how they disperse once the rocks weather. This has implications for the land, environment and mineral identification.

To achieve the objectives, the study will comprise three components:
1) Fieldwork: Collection of representative small samples from drill holes stored at exploration sites, stratigraphic sections and outcrops;
2) Laboratory work: Analyses using various laboratory techniques to help define the mineral and chemical composition of the rocks; and
3) Method development: Microanalytical methods for in-situ measurement of trace elements of mineral phases (apatite, pyrite, feldspar etc) within host-, footwall-, and hanging wall sedimentary rocks.

Summer student may be employed to help geologists in the field. Contract may be put in place to help for sample collection and analysis. Contracts are placed following federal and territorial contracting practices and local organizations and companies are encouraged to bid.

This project will be conducted in partnership with the Northwest Territories Geoscience Office. Community visits are ongoing, and discussions will occur with the Land Corporations, Resource councils and Band councils with regards to the results of the studies. Several territorial and federal reports and theses will be available to the public; and results of the project will be presented at public conferences during the length of the project.


The fieldwork for this study will be conducted from July 12, 2011 to September 30, 2011.
