In the Taiwan orogen, Cenozoic passive-margin development on the flank of the Eurasian plate resulted in repeated phases of extension with the formation of faults and associated stratigraphic variations. Extensional faults are found with great lateral extent throughout the fold-and-thrust belt of western Taiwan. Pliocene through present-day shortening in the area, however, has resulted in fold-and-thrust geometries that show a history of interaction between early normal faults and later thrust faults.We evaluate the structural style and kinematics of contractional deformation in the fold-and-thrust belt of western Taiwan by using an inversion-tectonics model. Four cross sections are presented to illustrate the interaction of normal faults and thrusts in this area. Our study suggests that the contribution of thick-skinned tectonics to the structure of the fold-and-thrust belt of western Taiwan is not less than that of thinskinned tectonics. The structural style in the fold-and-thrust belt of the Taiwan orogen is related to inversion tectonics.
