Lithological and Stratigraphic Relationships of the Swayze Area, Abitibi Greenstone Belt Published Tuesday, 19 December 2017

This work is part of the multiyear Metal Earth project carried out by MERC (Mineral Exploration Research Centre, Laurentian University, Sudbury) to refine the geological knowledge of the Abitibi greenstone belt. The project is designed to attempt to understand why greenstone belts, such as the Abitibi, have many mineral deposits, whereas belts, such as those in the Wabigoon Subprovince to the west, have fewer deposits per unit area. Given the broad similarities in rock types at surface, the answer to the question likely lies in the mid to lower crust and/or the mantle. Therefore, Metal Earth is imaging the entire crust in the Swayze area along “transects” oriented perpendicular to the strike of major units and structures, using reflection seismic, magnetotelluric and gravity surveys. Geological mapping is also being done along the transects, to provide an up-to-date base for interpretation of the geophysical surveys.
