EPSC 210. Introductory Mineralogy.
Credits: 3
Offered by: Earth & Planetary Sciences (Faculty of Science)
This course is not offered this catalogue year.
Description
Elementary crystallography, chemistry and identification of the principal rock-forming and ore minerals, in hand specimens and using optical microscopy. Demonstrations of other techniques applied to the identification of minerals and to the analysis of their composition and structure. Optional 2-day field trip.
- Fall
- 2 hours lectures, 3 hours laboratory
- Prerequisite(s): CHEM 110 or equivalent, or permission of the instructor.
- A nominal fee is charged to cover expenses of materials and supplies for identification kits (pen magnet, streak plate, hand lens and acid bottle) used to identify minerals during laboratory exercises.
- Des frais seront prelevés pour couvrir l'usage des collections d'enseignement et les accessoires (loupe, aimant, bouteille d'acide chlorhydrique dilué, plaque de porcelaine) essentiels à l'identification des minéraux pendant les travaux pratiques.
Most students use Visual Schedule Builder (VSB) to organize their schedules. VSB helps you plan class schedules, travel time, and more.

Description
Basic concepts in geochemistry and the application of geochemical principles of chemistry to geological subdisciplines. Particular emphasis on origin of elements, controls on their distribution in Earth and cosmos, isotopes, organic geochemistry and water chemistry. Application of phase diagrams to geology.

EPSC 547. Modelling Geochemical Processes.
Credits: 3
Offered by: Earth & Planetary Sciences (Faculty of Science)
This course is not offered this catalogue year.
Description
Modelling will be applied to construct equilibrium and transport models that quantitatively investigate geochemical processes occurring on Earth and other planets. Topics include, but are not restricted to: box modelling of the transport of elements between geochemical reservoirs, chemical reactions of components during flow through systems, interactions between multiple, competing reactions and/or processes. Model applications will vary from the core and mantle of planets to their surface environments and humans' impact upon them.
- Fall
- 3 hours lectures
- Prerequisites: EPSC 220, MATH 222, or permission of instructor.

Description
Investigation of the primary mechanisms causing the diversity of igneous rock compositions on the Earth, other planets, asteroids, and meteorite parent bodies.
- Winter
- 2 hours lectures, 1 hour seminar
- Prerequisite: EPSC 423

Subjects of special interest in my teaching include cosmochemistry, high-termperature geochemistry, introductory geochemistry, magmatic processes of igneous rocks and geochemical modelling.
Research
Investigates igneous processes through experimental geochemistry in laboratory. Goal is to understand the structure, thermodynamics, and transport properties (diffusion and viscosity) of silicate melts and to apply this knowledge in the investigation of igneous petrogenesis. Together with his students, Dr. Baker is studying the thermodynamics of silicate melts at pressures to 2.0 GPa, the partitioning of trace elements between amphibole and melt, the structure of halogen-bearing silicate melts, the effects of melt composition on zirconosilicate crystallization, the effects of volatiles on granitic melt viscosities, the controls and effects of magnetite crystallization in basaltic compositions, and gold solubility in melts and its partitioning between silicate melts and sulfides. Future projects include studies of diffusion in silicate melts at high pressure, in situ spectroscopic studies of melts at high temperatures and pressures, and determination of partitioning water between silicate melts and nominally anhydrous crystals.
