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

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.
