Research area

Igneous petrology, experimental geochemistry

Research interest

My research aims to understand the present state and evolution of the Earth's mantle by high-pressure, high-temperature experimental studies and thermodynamic modelling. My particular interest is in the role of volatiles in mantle processes, and how volatiles such as carbon and water behave in the mantle.

Current projects include experimental studies on (1) the buffering capacity of mantle peridotite and implications for diamond formation, (2) melting of carbonated harzburgite, (3) interaction of carbonatitic melts with mantle peridotite, and (4) the synthesis of diamond in systems analogous to nature. 

Recent graduate student projects include (1) the near-liquidus phase relationships of primitive minette, (2) the melting behavior of mica-clinopyroxenites as models for vein assemblages in the lithospheric mantle, (3) the stability of phlogopite in peridotites, and (4) the effect of halogens on hydrous mantle melting.

Recent undergraduate projects have been on melt inclusions, diamond growth, and alkaline igneous rocks in Alberta and British Columbia.

Research opportunities

PhD and MSc projects are available for students interested in experimental studies of mantle processes and products.

Courses

EAS 100 - Planet Earth

Introduction to the origin and evolution of the Earth and the solar system. Introduction to plate tectonics and the rock cycle. Simple energy balances and interactions between radiation and the atmosphere, land, oceans, ice masses, and the global hydrological cycle. Evolution of life, biogeography, and global climate in the context of geologic time. The carbon cycle. Human interaction with the Earth. Mineral and energy resources. This course may not be taken for credit if credit has been obtained in EAS 105 or 201.

Winter Term 2022
EAS 201 - Earth Science I

A non-laboratory introduction to the origin and evolution of the Earth and the solar system. Introduction to plate tectonics and the rock cycle. Simple energy balances and interactions between radiation and the atmosphere, land, oceans, ice masses, and the global hydrological cycle. Evolution of life, biogeography, and global climate in the context of geologic time. The carbon cycle. Human interactions with the Earth. Mineral and energy resources. This course may not be taken for credit if credit has been obtained in EAS 100 or 210. (Note: EAS 201 and EAS 200 are considered to be equivalent to EAS 100 for prerequisite purposes).

Winter Term 2022
EAS 331 - Igneous Petrology

A survey of igneous rocks from the ocean basins and the continents; their field settings, classification, petrography, mineralogy and chemistry; magmatic processes and petrogenesis; problem solving and laboratory work on major rock suites. Prerequisites: CHEM 102 or SCI 100 and EAS 232 and prerequisite or corequisite EAS 320. [Faculty of Science]
