Jonathan Cloutier

Thesis Title:
Geochemistry of the apparently non-mineralized Wheeler River and mineralized Millennium and Eagle Point alteration systems, east Athabasca Basin, Saskatchewan: implications for uranium exploration.

Jonathan graduated with a B.Sc. (2002) and M.Sc. (2004) in geology from Université du Québec à Montréal, Montréal.

His research is centered on the significant differences between barren alteration systems and both sandstone-hosted and basement-hosted uranium mineralized alteration systems in the Athabasca Basin. This will enable him to identify the key processes lacking in the barren systems that result in ore generation and the duration of events required to generate ores. Specifically, the project will include analytical procedures available at the Queens Facility of Isotope Research (QFIR) including: (i) characterization of various alteration zones, (ii) characterization of the fluids associated with different stages of alteration, (iii) absolute timing of alteration events and (iv) elemental compositions of whole-rock and isotopic compositions of fluid tracer elements such as Li, B, Nd, Sr and Pb.

Dr. Merline Djouka-Fonkwe

Merline Djouka-Fonkwe received her B.Sc., M.Sc., and First year doctorate (DEA) degrees at the University of Yaounde I, Cameroon. Her works contribute towards the study of the eruptive dynamisms along the Cameroon Volcanic Line. Merline obtained her Ph.D degree at the Institute of Mineralogy and Crystallography (University of Wurzburg, Germany; 2005), thanks to the German Academic Exchange Service (DAAD) scholarship.

Currently, Merline is a postdoctoral fellow in the QFIR group. Half of her time is spent decrypting key parameters that have played a role in fixing uranium in various deposits and what has been mobilized from them into various aquifers as part of an extensive program in examining the critical steps associated with deposit formation and deposit preservation. The methods used are stable and radiogenic isotopes, trace elements, crystal chemistry and petrography. The other half of her time involves the comprehension of normal diagenetic processes of ores and gangue minerals that result in mobilization of components from mineral surfaces. The aim is to develop new analytical techniques that will identify concealed deposits.

Andrew Bukata

Thesis Title:
Reconstructing Environmental Change Using Stable Isotopes (d15N and d13C) and Metal Contents of Tree-Rings (Ph.D. 2007)

Andrew completed a B.Sc. in Chemistry at The University of Western Ontario and then worked for Atmospheric Environment Services before returning to complete a M.Sc. in Environmental Geochemistry at Trent University/Atomic Energy of Canada Limited. His Ph.D. thesis focused on the application of stable isotope (15N and 13C), ring-width and elemental concentration variations in tree-rings as recorders of changes in biogeochemical cycling.

Examining nitrogen cycle perturbation following tree-clearing and land-use change, Andrew established that tree-ring d15N values faithfully recorded the timing of the event (Bukata and Kyser, 2005). This suggested that trees could serve as long-term monitors of the nitrogen cycle. The paper was featured on the cover of Environmental Science and Technology and was the subject of an online news story (http://pubs.acs.org/subscribe/journals/esthag-w/2005/sep/science/pt_tree...).

Subsequent work demonstrated that tree-ring d13C values and d15N values record the effect of urban pollution and provide both a chronology of 20th century anthropogenic pollution in southern Ontario as well as indicating the spatial extent of the impact (Bukata and Kyser, 2007).

Fire is a natural occurrence that can alter biogeochemical cycles in the soil. In collaboration with Tom Al at the University of New Brunswick (http://www.unb.ca/fredericton/science/geology/tal/tal.htm) we showed that tree-ring d15N values record a shift coincident with the fire-event. Laser ablation microsampling in a fire-scarred tree showed high radial variability in elemental concentration consistent with the tree recording localized fire-induced alterations to the geochemical cycling of elements in the soil. This study demonstrated that tree-ring elemental variations have the potential to record the timing and extent of past forest fires (Bukata, Kyser and Al, in review).

Combining carbon isotope analyses and elemental concentration measurements on annual growth rings, Andrew showed that while oak are passive monitors of changes in non-nutrient elemental availability, nutrient concentrations when the tree is stressed are not necessarily related to environmental bioavailability (Bukata and Kyser, in review).

Mike Cooley

Thesis Title:
Structural Geology and Fluid History of the Livingstone Range Anticlinorium, Southern Alberta Foothills.

Mike's research combines detailed structural analysis of a major hangingwall ramp anticline and its associated thrust faults, fault-propagation folds and cross faults, with the isotope geochemistry and fluid inclusion analyses of veins associated with specific fault zones. Geochemical data from the fault-related veins should reveal the types of fluids that were flowing through the structure during its development, and provide information on the mechanics and timing of fluid migration and the entrapment of hydrocarbons.
