Abstract

Seismic exploration of orogenic belts has significantly improved our understanding of their geodynamic evolution and structural architecture. A complete orogenic cycle includes two distinct phases: 1) orogenic growth related to convergent plate boundaries that involve major lithospheric-scale compressive deformation and tectonic burial and 2) late-to-post orogenic collapse, achieved by extension and/or erosion exhuming the root of the orogens. The deeply exhumed Paleoproterozoic (1.8Ga) Trans-Hudson Orogen (THO) went through the entire process of orogenic growth and collapse, thus preserves many features observed remotely within modern orogens. Seismic sections from the western margin of the THO (LITHOPROBE, COCORP, EXTECH-IV) are of good quality and image the orogen on different scales.
