Leo (Seungmin) Lee research project
Leo is examining the evolution of magma at Mount Pinatubo, Philippines. The eruption of Mount Pinatubo in June, 1991, was one of the largest in 20th C. The magma was highly oxidized to contain anhydrite phenocrysts and high SO42- in melt inclusions. I conducted studies on the 1991 eruption products (see Pinatubo work). Leo is re-examining the eruption products using zircon grains and tracing the change in magmas by examining older eruption products including ~ 4 Ma volcanic rocks.

His work is reported in Ottawa-Citizen newspaper on Sept 22, 2018. pdf

Field work in Philippines

Leo started a MSc thesis project in the summer of 2016. We completed the field work with help of Theophilus Valera of the University of Philippines around the Pinatubo volcano, Philippines, in December, 2016.
