| 中文摘要: |
| 微细浸染型金矿是中国西部印支褶皱区的主要金矿类型。浅变质浊积岩建造、区域性地热异常和配套的断裂系统是成矿最基本的条件。研究认为,该区具有寻找这类金矿的良好前景,并指出了找矿方向和找矿标志。 |
| 英文摘要: |
| The mojor type of micro-disseminated gold ore deposit in the west China is formed by epithermal groundwater fluid. The gold-bearing turbidite is the source bed. Magmatism, high palaeo-geothermal gradient and the regional geothermal anomalies caused by strong tectonic compression are the motive force to migrate ore materials. The relavent fracture system is the basical strctural condition for Au metallogeny, i. e. ore fluid is chanelled by major fractures but the gold ore deposit is located at the dilatant parts of the sub-scaled compressional-tortional fractures. Detailed study reveals that geological conditions in the West China is propitious for micro-dissminated gold metallogeny. It should be a target area. Prospect and exploration can be carried out along big fractures which are often boundaryes of different geological bodies and the metallogenic marks are designed. |
