Calcareous Nannoplankton Biostratigraphy and Stratigraphic Correlation of the Mesozoic and Cenozoic Sequences in Central, Southern, and Eastern Taiwan

Wen-Rong Chi

Abstract

During the past three decades, biostratigraphy and stratigraphic correlation were studied in Taiwan with framework mainly based on Foraminifera. Recently, a new biostratigraphic tool, calcareous nannofossil, has been introduced and successfully applied to biostratigraphy, stratigraphy, and oil exploration here.

The lithology in central and southern Taiwan is characterized by facies changes and the lack of distinctive marker horizons, especially in the Tainan and Kaohsiung areas. It is very difficult to subdivide these sequences and make correlations based on the lithostratigraphic study alone. Fortunately, most of the sediments are rich in nannofossils, and it is now possible to solve the above problems.

In this paper some very encouraging results obtained from the sediments of central and southern Taiwan are presented. A total of 24 calcareous nannoplankton datums and 20 zonations have been recognized and proposed from the sediments of the studied areas, the listed as follows in ascending order:

Based on these data, not only stratigraphic correlations can be made among the sections and areas, but also can be understood their stratigraphic relations with the rest of Taiwan. Furthermore, the Oligocene/Miocene, Miocene/Pliocene, Pliocene/Pleistocene boundaries can be recognized as well.

There are three unconformities that have been recognized in the Peikang area, and one in the coastal Range, eastern Taiwan. These data also provide basis for the interpretations of the geohistory and the tectonic movement of central, southern, and eastern Taiwan.
