Geochronology and cooling history of the Nain Anorthosite Complex from an argon-40/argon-39 study
The Nain Anorthosite Complex is a Proterozoic plutonic suite in Labrador. This complex is composed over 24 anorthositic and troctolitic rocks, but its regional geochronology and tectonic environment were uncertain.
