#1: Dominant Depositional Processes in the Pliocene Taiwan Strait

The Western Foreland Basin underlies the Taiwan Strait. In project 1, we used outcrop descriptions and sediment geochemistry (Carbon-13 of organic carbon in mudstone) to determine the dominant controls on sedimentation in the Pliocene. From this work, we developed a theoretical model for the tropical cyclone (typhoon) beds in the strait, and showed that typhoons completely dominate sedimentation in shallow-marine positions in the strait.

#2: Paleoclimate Signals in Early Pleistocene Shallow-Marine Strata, Taiwan
Fig 3_edited.jpg

In this work, we use cyclostratigraphic analysis of Early Pleistocene shallow-marine records to demonstrate that it is indeed possible to preserve precession signals through the Early Pleistocene. This is possible through the use of detailed outcrop logging, and high-resolution paleomagnetic and biostratigraphic controls on depositional age.
