Abstract
By means of analyzing organic carbon
concentrations and isotopic compositions of
core sediments from Tsung-yeh, Ma-chou-hou,
Ta-lun and Hsin-chuang, this study
attempts to obtain the paleoecological,
paleoenvironmental and paleoclimatic informations of Chianan plain in Taiwan
since late Pleistocene. Moreover, such a
study is advantageous to the stratigraphic
correlations and explanations of local
structural activities.
This study confirmed that it is
applicable in stratigraphic correlations by
organic carbon isotope analysis. Likely the
boundary between Stage4 and Stage5
defined by this method is concordant with
that determined by long-term subsidence rate.
Compared to cores with Wu-Ku core in
Taipei basin, it can be concluded that the
coastal environments in western Taiwan
were strongly influenced by global sea level
changes, although there are significant
neotectonic differences.
