Key Points
  • Thermometric quantification betweenfaulted and undeformed rocks are compared with numerically calculated shearheating during thrusting
  • Distributed cataclastic flow of alarge shallow thrust (5‐7 km depht) produces a persistent temperature incrementof few tens of degrees
  • Higher and more localized temperature increase(50‐150 degrees) requires seismic slip
