The purposes of this project are summarized as follows, (1) establishment of biostratigraphy and correlation of the Upper Permian and Lower Triassic, and (2) examination of the Permian palaeobiogeography in Thailand. The surveyed areas are represented by the following three areas; namely (1) Lampang area, (2) Loei (& Chiengkan) area, and (3) Chumpon -Surasthani area. In the Lampang area the Uppermost Permian ammonoids and also the Lower Triassic ones are investigated from impure limestones and mudstones, respectively. The boundary between the Permian and Triassic is contacted by a fault in this area but the faunal break seems to be not so remarkable. In the Loei (& Chiengkan) area, the Lower Permian, Upper Carboniferous, and Devonian fossils are found from limestones and mudstones. In the Chumpon-Surasthani area Triassic corals and brachipods are investigated in the organic reef limestones. The brachiopod fauna is closely related with that of the Lampang area. Permian fusulines and Carboniferous brachiopods and pelecypods are investigated. These faunas are very important for examining the change of palaeoenvironment and palaeobiogeography in late Palaeozoic and early Mesozoic times in the southern realm of the Asian Tethys.

本项目的主要目的是：（1）建立泰国上二叠统和下三叠统的生物地层学和对比;（2）研究泰国二叠纪古生物地理。调查区域由以下三个区域代表;即（1）南邦（Lampang）区域、（2）洛伊（& Chiengkan）区域和（3）春蓬-素拉斯塔尼（Chumpon -Surasthani）区域。在南邦地区，分别从不纯的石灰岩和泥岩中研究了上二叠统和下三叠统的菊石。该区二叠系与三叠系的界线由一断裂接触，但动物群的间断似乎并不明显。在洛伊（和清干）地区，下二叠统、上石炭统和泥盆纪的化石被发现于石灰岩和泥岩中。在Chumpon-Surasthani地区，对有机礁石灰岩中的三叠纪珊瑚和腕足动物进行了调查。腕足动物区系与南邦地区密切相关。研究了二叠纪的类和石炭纪的腕足类和盘足类。这些动物群对研究亚洲特提斯南部晚古生代和早中生代的古环境和古生物地理变化具有重要意义。
