【摘要】 研究表明 ,测氡在区域构造稳定性研究中是一种最经济、便利、省时又可靠的地球化学测试手段。在第四系覆盖区 ,它不仅可以确定覆盖层下断裂网络的空间格架、断层产状、断层的相对活动性 ,而且还能为地震预报提供重要信息。在滇西北北部区域构造稳定性研究中 ,运用测氡手段首次揭示北西向中甸 -永胜断裂的存在、玉龙雪山的隆升机制和为工程区及其外围区域构造稳定性进行客观评价提供了保证更多还原

【Abstract】 Radon measurement is an economical, convenient, timesaving and reliable geochemical method. In the Quaternary cover area, it determines not only the frame, the occurrence of the faults under the cover, but also the relative activities of the faults and the forecast of the earthquake. In the study of regional tectonic stability, the method has solved many important problems such as the regional tectonic frame, the occurrence of the faults under the cover, and the relative activities of the faults. It ensured the perfect result of the study. Its successful application to the study of the primary stage of key engineering region and its fringe area. It is worth to be widely used in the study of regional tectonic stability.更多还原
