<p> The Thelon Tectonic Zone is a major structural,
metamorphic and lithological feature of the Precambrian
Shield in the Northwest Territories. Situated within this
Zone is a 30 square kilometre plutonic body. Rubidium-
Strontium whole rock geochronology yields an age range of
1650 - 2200 Ma for the emplacement of this pluton. Field
and petrographic evidence indicates that the pluton has
suffered post-emplacement deformation, representative of a
late Proterozoic metamorphic event. Major and trace
element geochemistry suggests that this high Ca,
ferrogranodiorite-tonalite intrusive body is associated
with a subduction-related, continental margin tectonic
environment. </p> / Thesis / Bachelor of Science (BSc)
