A study of the relationship between the crystal-chemistry and morphology of millerite from magmatic ore deposits

I completed my B.Sc. (Hons.) in geology at Laurentian University in 2017, with my thesis being the characterization of two new minerals from Mont St. Hilaire, under the supervision of Dr. Andy McDonald. My current research is focused on factors that influence mineral morphology. Specifically, the crystal-chemical controls on the morphology of millerite. The goal of this project is to determine what causes the millerite in magmatic sulphide deposits such as those in Sudbury and a handful of other localities worldwide to exhibit a platy morphology, whereas the majority of hydrothermal occurrences of millerite show an acicular morphology.
