| 中文摘要:贵德盆地位于青藏高原东北缘黄河谷地之中, 四周环山, 为新生代断陷盆地, 地貌单元位于青藏块体, 地处祁连、昆仑和秦岭三大褶皱系交汇地带; 新构造活动强烈, 发育一系列NWW向、NW向及NNW向断裂, 为区内高温地热系统提供了较好的地热地质条件。区内地热显示类型多样, 水热活动剧烈, 尤其是盆地西部的扎仓寺热田, 水温高达 93℃, 蕴藏着丰富的地热资源。但是由于客观条件限制, 区内地热资源的开发利用及相关研究尚有不足之处。 |

| Abstract:Guide basin belongs to Cenozoic period fault ba-sin, which is surrounded by hills that located in the Yellow River valley, northeastern margin of the Ti-betan Plateau; from the perspective of geomorphicu-nits it is located the QingHai–Tibet block, which among the Qilian–Kunlun–Qinlingorogenic belts. The study area have a series of faults in the NWW, NW and NNW direction, the intense neotectonic activity provides good geothermal geological conditions for high temperature geothermal system. There are vari-ous types of geothermal manifestation in study area, and have intense hydrothermal activities, especially in the west of the basin - Zhacangsi thermal field, where the water temperature is as high as 93℃. However, limitedby the objective conditions, the development and utilization of geothermal resources in the area and the related research are not yet perfect: |
