Constraints on the timing of thrusting during the Eurekan orogeny, Canadian Arctic Archipelago: an integrated approach to thermal history analysis
Thermochronological constraints on the timing of hanging-wall cooling across thrust faults can be interpreted in terms of fault movement under certain circumstances. Vitrinite reflectance data can be used to identify those circumstances and, in addition, provide constraints on the timing of fault mo...
