Expertise and areas of study
Dr. Tsilavo Raharimahefa's expertise is mainly in the field of structural geology and tectonic evolution of both oceanic and continental lithospheres. He also focuses on the application of geochronology and lithogeochemistry to various problems in tectonics, and application of Remote Sensing and Geographic Information Systems (GIS) in geological mapping, structural analyses, mineral exploration and geological modeling, neotectonics and tectonic geomorphology.
His current research topics include: 1) understanding of continental rift initiation and understanding of the interplays between Quaternary volcanism and pre-existing Precambrian basement structures; 2) kinematics of shear zones and emplacement of syntectonic granitoids; 3) Interplays between structural features, climate change, and landscape evolution; 3) Remote sensing and near-surface geophysics of high-strain zones; and 4) Origin and tectonic significance of deformation bands in Karoo sandstone.
Prior to joining the University of Regina, Dr. Raharimahefa was a Postdoctoral Fellow at Laurentian University, Ontario (2009-2011), and Visiting Assistant Professor at Earlham College, Indiana USA (2008-2009).
Dr. Raharimahefa is Editorial Board Member of “Sustainable Geoscience and Geotourism” and “Madagascar Conservation and Development”
