| Formation and Evolution of Thrust in the Wedge of Subduction Zone:Experiment Research on Tectonophysics Modeling |
| Tectonophyscis modeling is provided with special advantages,which rebuilding process and mech-anism of different structural phenomenons in the lithosphere and companing with the nature ones.Therescarches on geometries and kinematics of formation precess of wedges and its bottom thrust systemswere take as the main aim of the experiment,the different friction strength and different insetionthickness change were used as boundary conditions.The experiment confirmed underplating in the bot-tom of wedge. Different friction strength and insertion thickness hae the influences on the formation,evolution and consitution of the front edges,the interior and base thrusts of the accretionary wedge asfollows:①the distances among thrust systems of the front edges of the wedge increare by base frictionstrengthenning;②when base friction strengthenning,thrust imbricate fan of the accretionary frontedge appers as lealing imbricate fan,conversely ,as traiding imbricate fan;③insertion thickness has aprefound effect on the formation and evalution of the everse thrust with wedge. |
