| Research Abstract |
This project aims at finding new geomorphological methods to estimate crustal movements and improving the accuracy of measurement on estimating crustal movements. For this, following five items were studied. 1. Coastal terrace : What kind of shore features are most valuable as the indicator of former sea-level was examined. 2. Fluvial terrace : A new method of estimating vertical land uplift was developed. This method is based on the idea that the height difference between the post glacial and last interglacial river floors or between the last glacial and penultimate glacial river floors shows vertical uplift value during the period concerned. 3. Active fault : The method of searching active faults beneath the shallow sea or lake was examined. 4. Landform of mountain : Numerical data of height of mountains were used for estimating the mean rate of uplift. 5. Correlative strata : Facies and thickness of correlative strata to the mountain topography were studied for estimating the value of mountain uplift.
