| Abstract | The present study is a small part of Truong Son mountainous orogenic belt run along from North to the South of Vietnam. It has been listed the potential geothermal resource of Vietnam with measured and inferred temperature range to change from 95oC to 138,1oC at the depth smaller than 1 km. The geothermal manifestations in the area are located along the valley Kien Giang stream. A boiling reservoir at the depth causes geothermal manifestations such as hot water, gas and hot ground. The distribution of geothermal manifestations and analysis results showed that it can be controlled by faults and fractures in an E-W, N-S direction. Some areas of the stream valley, bedrock was brecciated, altered and covered by geothermal sinters. The reservoir reserve calculated results based on the geological, topographical, tectonic factors and the comparison of Vietnam geothermal resources to show up that it can be built the pilot binary cycle geothermal plant with minimum capacity 4,129 MW (90% probable), maximum capacity: 13,678 MW ( 50% probable). |
