Alicia Escribano – PhD candidate, Memorial University
Magmatism and VMS Formation, Victoria Lake Supergroup
Alicia’s research focuses in the Victoria Lake Supergroup (Newfoundland) VMS deposits and understanding their magma petrogenesis, tectonostratigraphic setting, and evaluate the relative roles of crust-mantle interaction and basement contamination in the genesis of the rocks hosting mineralization. This is accompanied by mineral scale zircon petrochronology, and CA-TIMS U-Pb geochronology and mineral chemistry (e.g., Ti-in-zircon), that coupled with isotope geochemistry serves to further evaluate petrology of the host magmatic rocks, inclusion assemblages in zircon to understand potential metal enrichment processes, and physicochemical conditions of magma formation and relationships to VMS (e.g., oxygen fugacity, temperature).
All the above provides a better understanding of the basement type, physicochemical conditions of magma, the relationship of crust-mantle interaction and secular evolution, and how this influenced the metal budgets, and siting and style of VMS mineralization in the Victoria Lake Supergroup.
Alicia graduated with a Bsc. Hon. in geology in 2010 from the Universidad de Concepcion, Chile, and worked for several years in the Chilean porphyry copper mining industry. She finished her M. Sc. in Geology at Acadia University in 2021 and is now part of the CREATE team while achieving a Ph.D. at Memorial University.
