地震及活斷層研究(車籠埔斷層之活動性與運動學研究)─台灣西部新構造運動與地震機制研究 (II)

This project is one of the counter-part
projects of the Sino-French cooperation in
studying the structural evolution of the
collisional mountain belt in Taiwan.
The neotectonics of the Taiwan mountain
belt is mainly controlled by the oblique
convergence between the Eurasian plate and
the Philippine Sea plate. In addition to this
mechanism, most of foreland structures are
strongly influenced by the existence of the
Peikang and Kuanyin structural highs. The
foreland structures of Taiwan in association
with this tectonic events can be briefly
summerized, from the north to the south, as:
The northeastern Taiwan is characterized by
the escape structures. The Taoyuan-Linkou
Tableland represent a relatively stable
structures sitting on the Kuanyin High. The
Hsuehshan-Chuhuangkeng area is
distinguished by squeeze-out or pop-up
structures between the two structural highs,
the Tatu and Pakua Tablelands are relatively
stable, sitting on the Peikang High. The
Yushan area is characterized by a transfer
zone and the Chishan-Pingtung area is also
marked by the escape structures.
The formation of these structures are in
accord with the field observations and
paleomagnetic data.
