Objective(s): The Slave Province (SP) is generally characterised by a shallow level of erosion and therefore, the deeper parts of the Slave crust are rarely exposed and can, in the most part, only be studied indirectly. However, reconnaissance mapping has highlighted the presence of an extensive high grade (deep crustal) terrane in the MacNaugthton Lake area. The objective of this project is to explore fully the relationship between the high grade metamorphism and granitoid rocks. Examination of this problem will contribute towards a better understanding of the formation of the lower crust within the Slave Province.
Project Description: The researchers will achieve detailed mapping of granite- metasediment contacts by relying on detailed documentation of mineral asseblages, textures, metamorphic grade, and relative timing of the meta-sedimentary and meta-igneous rocks in the MacNaughton Lake area. Isotope U-Pb studies of granite and metasediment minerals will be used to constrain the absolute timing of intrusion and metamorphism. Rock samles for this work will be collected using a hammer.
