He
is currently Senior Geologist at the Ontario Geological Survey. After his
graduation, we kept working together a variety of projects including a study of
detecting concealed kimberlites, the origin of
spontaneous potential anomalies over metallic deposits, and the process of
element transfer from deeply buried deposits to the surface media. We also
co-supervise students.

Brauneder, K., Hamilton, S., Hattori, K., 2015. Geochemical processes in the
formation of ‘forest rings’; implications for mineral exploration for concealed
deposits (Paper #15-EC-360R).
In press, Geochemistry: Exploration, Environments and Analysis.
A thesis project of Kerstin
Brauneder (MSc, 2012) was co-supervised by Stew and myself. To understand the
process of element movements from metallic deposis to surface media, we
examined forest rings as analogy. Forest rings form as reduced gases (methane
or H2S) emanate in the centre and disperse to the exterior.
