Kinematics of rock deformation

The dynamic evolution of the System Earth is chiefly controlled by internal generation and loss of energy, evident by plate-tectonic and magmatic processes, and external energy gain such as meteorite impact processes. An understanding of these processes, on variable length and time scales, underlies my research. Specifically, I propose to wok on: (1) analysis of fault systems and their effect on the activity of volcanic centres in the Central Andes (NW Argentina); (2) crustal deformation of orogenic belts, notably the Eastern Penokean Orogen (Ontario); and (3) formation of complex impact craters (Haughton, Devon Island, and Sudbury, Ontario). Because of their significance for geological hazard assessment and localizing natural resource deposits, these research fields have strong socio-economic importance. Key to all projects will be the visualization of the three-dimensional (3-D) structure of deformed rock volumes, restoration to their pre-deformational shapes, and analysis of deformation mechanisms. This approach promises to result in a better understanding of dynamic rock deformation from the mm- to the crustal scales, and on various time scales, more specifically, eruptive triggers of volcanic complexes, transport and emplacement of endogenic melts, stress accumulation, ore deposit genesis and impact crater formation. In the long run, I intend to close the gap between geological field and the numerical modelling studies by linking structural geological ground truth gleaned from process-oriented studies of natural laboratories with quantitative kinematic restoration of deformation and (analogue) modelling studies. This approach contributes also to generating more realistic models of rock deformation. My research on the formation and localization of ore deposits, addressed in collaboration with industry, will contribute to designing process-oriented exploration strategies. Neo- and volcanotectonic studies will help in mitigating potential seismic and volcanic hazards, most importantly for highly populated areas.
