Oxygen
Isotopic
Composition of the Tagish Lake Carbonaceous Chondrite:
- Laser Fluorination of anhydrous phases (olivine and
pyroxene concentrates) with the purpose of delineating a
Tagish Lake Anhydrous component mixing line
- Laser fluorination of matrix phases assemblages
(serpentine, saponite, magnetite)
- Fabrication of a sample transfer airlock to
allow for analysis of "reactive" phases using conventional
laser fluorination techniques
-
Modal Analysis and Geochemistry of
Granitic Inclusions in the Vishnupur and Adzhi-Bogdo Type LL6 Chondrite.
-
The origin and petrogenesis of
Adirondack fayalite augite syenites; a study of source material and
recycling of granitic rocks late in the Grenville Orogeny.

Current
Intellectual Interests
- Mass-independent fractionation
of sulfur isotopes; signatures in Archaean sedimentary
rocks, volcanic horizons, and diamonds!!!
- Specifically, the mechanisms
of preservation of such signatures in the Archaean
ocean, and flux of MI signatures into hydrothermal and
diagenetic fluids.
- Mass-independent fractionation
of oxygen isotopes in the modern atmosphere and
preservation in terrestrial reservoirs
Past
Research
-
Geology and Geochemistry of
Adirondack Fayalite Augite Syenites (BSc. Thesis).
-
Cerium oxidation state in apatites
from the Vishnupur and Adzhi-Bogdo Meteorites.
-
FTIR Quantification studies of
clay-quartz and clay-nepheline syenite mixtures.
