Abstract

Due to the low accessibility of high mountains in Taiwan, there is little knowledge of the geologic conditions in these areas. This paper is a part of the study sponsored by Remote Sensing Development Committee of Agriculture Council to collect geologic information in NengKaoShan Area, with a size around 1700 square kilometers. The area covers also a part of the ridge line of Central Mountain Range. The results show that there are more then 4000 landslides in this area. The area is in the Central Mountain Geologic Province with two old geologic formations, i.e. The Tananao Schists and Bilusan/Lusan Formation. The Tananao Shists Formation(incl. Taluko Belt and Yuli Belt) spans from Paeleozoic to Mesozoic time. The Pilushan/Lushan Formation was in Paeleo-Tertiary Perido. Eight lithologic units can be readily identified from both the satellite images and aerial photographs. They are denotated as Y, S, K, T, TM, Eh, M, and Qa. The K unit exists to the noth of SanChanSi, whereas the Y unit takes place to the south of SapoDanSi. In this year, GPS is used to position the outcrop when field works were conducted. It is concluded that GPS linked to a notebook computer is a good tool for improving the efficiency and potentially an important tool for automating field work.
