Fazilat Yousefi

Fazilat Yousefi is a Postdoctoral Fellow in the Department of Earth Sciences at the University of New Brunswick (UNB), specializing in geochemical and petrological studies of magmatic systems. Her current research focuses on Heavy Rare-Earth Elements (HREE) and Yttrium enrichment in Early Devonian A-type granites within New Brunswick, supported by the NRCan-NBDNRED project. Previous work includes a PhD study on Devonian adakitic porphyritic intrusive rocks linked to porphyry Cu-Mo-Au mineralization in the Northern Appalachians.

Education: PhD in Earth Sciences from the University of New Brunswick. Research interests span petrogenesis of magmatic rocks, rare earth element enrichment mechanisms, porphyry fertility indices, and the application of machine learning in mineral prospectivity mapping. She has conducted extensive field and laboratory studies, including zircon U-Th-Pb isotopic analyses, titanite and magnetite mineral chemistry, and melt inclusion analysis across North America and Iran.

Her work bridges magmatic processes and economic geology, with contributions to understanding critical mineral resources and the geodynamic context of porphyry systems. Research locations include New Brunswick’s Northern Appalachians and Iran’s Torud-Ahmad Abad magmatic belt.

Labs/Teams: Collaborates with Dr. David Lentz (UNB) and international teams studying magmatic-hydrothermal systems. Active in interdisciplinary projects combining geology, geochemistry, and computational methods.
