The proposed research will examine the possibility that Bear Creek         Foredeep evolved on thermally young continental lithosphere as a                result of collapse of an immature passive continental margin.  Research         will involve an integrated approach, combining geological and                   geochronological field investigations of selected areas with                    geophysical modelling of related gravity anomalies the Thelon Tectonic          Zone (infered suture) and two-dimensional modelling of the basin -              Thelon Zone system.  Models will be used to make first-order                    predictions concerning basin geometry and stratigraphic architecture of         basins formed on cold vs. warm lithosphere.  The models will then be            compared to the observed characteristics of Bear Creek Foredeep as a            method of evaluating the thermal condition of the lithosphere during            basin development.  Evaluating the thermal age of the lithosphere               during subsidence of Bear Creek Foredeep constitutes a critical test of         the hypothesis that passive continental margins may have been, on the           average, more short-lived than in younger times (cf. Hoffman and                Bowring, 1984).
