Inversion Tectonics in the Fold-Thrust Belt of the Foothills of the Chiayi-Tainan Area, Southwestern Taiwan

jian-hong Chen

Abstract

The Taiwan mountain belt provides a key for analyzing the relation with tectonic in an active compressional environment. Major thrust faults in the fold and thrust belt of the southwestern Taiwan usually related to reactivated normal faults. In southwestern Taiwan the grabens and basement hights are bounded by NNE-SSW and NW-SE trending normal faults. In study area the pre-existing normal faults usually reactivation and inversion to produced thrusting and folding since middle Pliocene. The compressive deformation by arc-continent collision in Taiwan . Structural interpretation of the study area is referred to as thick-skinned ,basement-involved tectonic.
