KONG XIANG-RU LIU SHI-JIE ZHANG JIAN-JUN LI ZONG-SHUN NIU QING-PO(Institute of Geophysics, Academia Sinica, Beijing 100101)PAN JIN-DIAN LIN SHENG-ZHAO(Geophys. & Geochem. Prospecting Team of Fujian Province, Fuzhou 350011)  
In 1986 and 1987 we have made low-frequency MTS in the eastern area of Fujian Province. The results are as following:1.An arising (i.e. diapiric structure) of asthenosphere was found in the upper mantle in both Fuzhou and Zhangzhou regions where lithosphere become thin and diapiric sub-structure exists at a depth of 20-30km. That means the geothermal activities are strong and hot springs connect with deep geothermal background thrre.2.There is a low-resistive zone with direction of N60°E from Huian to Longhai. Along the zone the geoelectrical structure is similar with that of the ocean crust. It is probably a suture of the old continent and the obducted oceanic crust.3.Two promising geothermal prospective areas were found in Yongchun and Tongan where the depths of highly conductive layers in the crust are obviously shallow. It is necessary to make more detailed investigation there.
