| Outline of Final Research Achievements |
This study investigated relative sea-level change since the Last Glacial Maximum (LGM) based on the analysis of incised-valley fills at the Tsengwen River, western Taiwan. The thickness of incised-valley fill deposits is approximately 180 to 200 m and its succession consists of upward-fining and upward-coarsening in ascending order. Radiocarbon ages obtained from the base of the deposits are around the LGM. Sediment accumulation rate was almost equal to the rate of eustatic sea-level rise. Accumulation of the deposits was recognized since around the LGM. The accumulation from the LGM to 17500 cal BP may have resulted from accommodation due to tectonic subsidence of the basin as well as glacio-eustatic sea-level rise. In addition, it was estimated that the rate of glacio-eustatic sea level rise increased since 15000 cal BP.
