摘要:
垭都—紫云断裂带是扬子陆块西南缘的一条重要的控制性边界断裂带,它控制着周围地区的盆地沉积及构造变形样式。以垭都—紫云断裂为界,贵州85%的地震发生在该断裂以西,说明该断裂带活动性较强,断层普遍在早—中更新世有活动,尤其是北段的垭都断层,为晚更新世断层,具有较强的发展能力。探测该断裂带中的断裂活动时期,对该断裂带的活动性评价具有重要意义。应用音频大地电磁测量(AMT)和Ra?法测氡进行综合测量,结合地质资料,研究该断裂带中垭都断裂的活动时期。其中Ra?法测氡首次对垭都—紫云断裂带进行测量,应用效果较为理想,为今后对该断裂带的其他断裂的测量提供可靠的理论支持和工作借鉴。
Abstract:
The Yadu-Ziyun fault zone is an important controlling boundary fault zone in the southwest margin of the Yangtze block, which controls the basin deposition and tectonic deformation pattern in the surrounding area. Taking the Yadu-Ziyun fault as the boundary,85% of the earthquakes in guizhou occurred to the west of the fault, indicating that the fault zone has strong activity. The faults were generally active in the Early-Middle Pleistocene, especially the Yadu fault in the northern section, which is a late Pleistocene fault with strong development capability. It is of great significance to detect the fault active period in the fault zone for the evaluation of the fault activity. The paper uses audio magnetotelluric measurement (AMT) and Ra? method to measure radon for comprehensive measurement,and combines geological data to study the active period of the Zhongyadu fault in the fault zone. The Ra? method is used for the first time to measure radon in the Yadu-Ziyun fault zone, and the application effect is relatively satisfactory, which provides reliable theoretical support and work reference for the measurement of other faults in the fault zone in the future.
