Scope of Project:

Project Theme: Chibougamau transect / magmas and mineralisation.

The Chibougamau area, when compared to the rest of the Abitibi Subprovince, has several unique characteristics i) fold-dominated architecture; ii) lack of komatiites; ii) unusual intrusions (layered complex and polyphased pluton); and, iv) in the broadest sense, a large amount of “intrusion-related” mineralisation.


Anticipated Outcomes:

For the duration of the project, the team will focus on i) revealing factors that controlled the formation of deposits in the Chibougamau area by comparing it with other greenstone belts; ii) comprehension of the role that magmas play in mineralising processes and in the transport of volatiles and metals in the crust; and iii) interpretation of the Chibougamau transect and 3D modelling.
