The principal investigator will study the petrogenesis of the anorthosite-mangerite association. He will integrate field, petrological, and geochemical techniques to determine the parental magmas and differentiation mechanisms of massif anorthosites, the causes of the anorthosite-mangerite association, the nature of mafic and oxide-rich lithologies, and the origin and significance of iron-titanium ore deposits. The work will be done in the St.Urbain/Charlevoix, Labrieville, and Morin regions of Quebec. The project will help geologists better understand the origins of this important group of igneous rocks.

首席研究员将研究斜长岩-锰矿岩组合的岩石成因。他将整合野外、岩石学和地球化学技术，以确定块状斜长岩的母岩浆和分异机制，斜长岩-锰矿结合的原因，基性和富氧岩性的性质，以及铁钛矿床的起源和意义。这项工作将在魁北克的St.Urbain/Charlevoix、Labrieville和Morin地区进行。该项目将帮助地质学家更好地了解这一重要火成岩群的起源。
