Abstract
Taiwan has been considered as a modern analog
of collision belt of the circum-pacific area. This
proposed investigation is mainly to focus on the study
of the neotectonics in the Taiwan Mountain Belt. 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. Around
these structural highs, the Quaternary tablelands in the
western Taiwan were developed and deformed. 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.
