Research Interests

Dr. Jiang's research interest lies primarily in using structures and fabrics preserved in Earth's crust and mantle, observed on small scales such as in field rock exposures, in hand samples, and under microscopes, to unravel large-scale tectonic deformation processes. He integrates fieldwork, laboratory microstructural and texture analysis, and numerical modeling in his research. He has developed a self-consistent micromechanical approach for modeling muti-scale fabric development during the deformation of the heterogeneous Earth's lithosphere. The approach provides a rigorous link between structural geology and tectonics. His group currently applies the approach to field areas in the Canadian Shield, the Central Orogenic Belt of China, and the North China Craton.

Dr. Jiang is also a Distinguished Professor at Northwest University, China, and supervises graduate students at Northwest.

Future Students

Dr. Dazhi Jiang is currently looking for Ph.D. and M.Sc. students to work on projects in the Canadian Cordillera and East China. The former project aims at better understanding the evolution of microstructures of mylonites, and the latter project strives to better understand the tectonic evolution of East China since late Cretaceous and its relationship with the thinning of the North China Craton. Interested students please contact Dr. Jiang for more information.
