About Prof Jérémie Lehmann

Research interests:

  • Evolution in the tectonics of orogens from the Archean to Paleozoic in the frame of secular changes through Earth’s history
  • Paleoarchean Earth: Barberton Granite-Greenstone Terrain
  • Mesoproterozoic Earth: Kunene Complex massif-type anorthosite
  • Neoproterozoic to Cambrian Earth: Pan-African orogen of the Damara and Dahomeyide belts
  • Mining exploration in orogenic belts

Teaching:

Second year:  Structural Geology: stress, strain, rheology, brittle and ductile deformation at tectonic plate scale to mesoscale. Includes four days field excursion in Johannesburg dome basement gneisses and greenstones and deformed Witwatersrand Supergroup cover.

Honours:  Tectonic Evolution of Mountain Building Areas: structural geology and rheology of the lithosphere. Microstructures. Excursion: Advanced Field Mapping (3 weeks)
