In November and December of 1990 and 1991, we took field survey in Thailand and Malaysia. We attempted to collect microfossils from the Middle Paleozoic to Early Mesozoic strata in the mentioned two countries. We described briefly micropaleontological Investigation In this interim report.1) Radiolaria from northern Thailand : We collected samples of chert and siliceous shale from the "Fang Chert" (Bunopas. 1981). We discriminated the Late Devonian to Early Permian radiolarians.2) Radiolaria from northeastern Thailand : We found Late Devonian to Early Carboniferous radiolarians from a sequence of greenish shale and chert which crop out near Ban Pak Chom. Furthermore, we discovered well preserved Late Devonian radiolarians from black cherts exposed along the Pak Chom-Loei Road and an abandoned manganese quarry of Phu Song.3) Radiolaria from southern Thailand : Well preserved early Middle Triassic radiolarians and conodonts were obtained from the bedded limestone exposed at Khao Chiak near Phatthalung.These micropaleontological evidences are vital to the understanding of the paleogeography and tectonic development of Southeast Asia.Rock samples from Malaysia are now in preparation.

1990年和1991年11月和12月，我们在泰国和马来西亚进行了实地考察。我们试图在这两个国家的中古生代至早中生代地层中采集微体化石。在这份中期报告中，我们简要描述了微体古生物调查。1）泰国北方放射虫：我们从“方燧石”（Bunopas. 1981年）。我们区分晚泥盆世至早二叠世放射虫。2）泰国东北部的放射虫：我们发现晚泥盆世至早石炭纪放射虫从一个序列的绿色页岩和硅质岩附近的Ban Pak Chom。此外，我们还发现了保存完好的晚泥盆世放射虫，这些放射虫来自于沿着Pak Chom-Loei Road和Phu Song废弃的锰采石场暴露的黑色硅质岩。在法塔隆附近的Khao Chiak出露的层状灰岩中，获得了保存较好的中三叠世早期放射虫和牙形刺，这些微体古生物学证据对了解古地理和构造发展具有重要意义。东南亚。马来西亚的岩石样本正在准备中。
