摘要: 野外初步调查结果表明,札达盆地不仅边界断裂存在较强烈的活动性,而且在盆地内部发现了较多的活动断层,同时还伴有大量的崩塌堆积。该调查结果为札达地区区域地壳稳定性的评价和青藏高原区域应力场的分析提供了宝贵的实际资料。Abstract: Preliminary field investigation of the Zhanda basin in the Ngari area, Tibet, indicate that not only the boundary fault is very active but also many active faults are newly found in the basin, and in addition, there are voluminous olistostromes. The investigation provides valuable information and data for the evaluation of regional crustal stability in the Zhanda area and analysis of the regional stress field of the Qinghai-Tibet Plateau.
