| 摘 要： | 对宁夏中卫南F201左旋逆走滑断层长度一直存在不同意见。通过八个方面的对比研究,本文认为F201断层长度至少是1709年中卫南7 12级地震破裂带的长度。该地震破裂带西起营盘水东,东到双井子,并扩展到刘岗井以东的石圈沟附近,近东西向延伸长110 km。由小红山—孤山子、西梁头—腰岘子沟、窟窿山—碱沟、青驼崖西—寺口子沟东及山羊场—刘岗井东5条次级剪切断层段组成。

| Abstract: | Up to now, there are different views on the length of F201 left lateral strike-slip fault in South of Zhongwei, Ningxia province. Through comparison study on the rapture belt of M7 1/2 South of Zhongwei earthquake in 1709 from eight aspects in this paper,it is ditermined that the length of F201 is at least as same as the rapture length of the South of Zhongwei earthquake in 1709. The earthquake rapture starts from East to Yingpanshui as west end and extends eastward to Shuangjingzi, then expands to nearby Shijuangou at east to Liugangjing, the overall east-west length of the rapture is 110 km. The rapture is composed of five secondary shear faults, Xiaohongshan-- Gushanzi, Xiliangtou-- Yaoxianzigou, Kulongshan-- Jiangou, West to Qingtuoai-- East to Sikouzigou and Shanyangchang--East to Liugangjing. |
