Research interests
Professor Soucy La Roche studies tectonic processes in convergence zones with a specific focus on the mid-crustal evolution of continent-continent and accretionary orogens. He uses a broad variety of methods to describe tectonic systems as comprehensively as possible:
- Field mapping
- Structural analyses (including microstructures and quartz crystallographic preferred orientation analyses)
- Metamorphic petrology (including petrography, thermobarometry and phase equilibria modelling)
- U-Th-Pb petrochronology on zircon, monazite,xenotime, allanite and titanite
- Lu-Hf geochronology on garnet
- Ar-Ar geochronology on white mica, biotite and hornblende
- Trace element geochemistry
So far, professor Soucy La Roche has applied his expertise to the Himalaya, the Grenville Province, the Superior Province, the Slave Province and the Canadian Cordillera. His full research profile is available in French.
