Expertise and areas of study:

Dr. Guoxiang Chi's expertise is mainly in the field of fluid geochemistry and hydrodynamics in relation to metallic mineralization and hydrocarbon accumulation, with emphasis on application of fluid-inclusion, stable isotope, and numerical modeling techniques.

His current research topics include: 1) Hydrodynamic linkage between shallow and deep-seated geologic processes and its control on mineralization; 2) Uranium mineralization systems in various environments, especially in sedimentary basins; 3) Au, Cu, Pb, and Zn mineralization systems in sedimentary, orogenic and magmatic-hydrothermal environments; 4) Diagenetic studies of sedimentary rocks, with emphasis on reservoir characterization and hydrocarbon migration and charging history.

Prior to joining the University of Regina, Dr. Chi worked as a Research Scientist at the Geological Survey of Canada (1996-2002), Research Associate at INRE-Georesources (1996), and Post-doctoral Fellow at the Geological Survey of Canada (1994-1995) and University of Quebec at Chicoutimi (1992-1993).

Dr. Chi is Associate Editor of "Ore Geology Reviews" and "Acta Geologica Sinica", and Editorial Board Member of "Journal of Earth Science" and "Geotectonica et Metallogenia", and has served as Associate Editor of "Bulletin of Canadian Petroleum Geology", Guest Editor for special issues of "Geoscience Frontiers" and "Ore Geology Reviews".
