么站断层位于垭都—紫云断裂带威宁—水城断裂段，是贵州西部地区活动性较强的断裂带，利用野外地质调查、浅层地震勘探、钻孔联合地质剖面等深、浅、表立体式多层次研究方法，对断层开展几何特征研究，分析其平面几何展布特征和深、浅、表构造关系，填补该断层隐伏区活动特征的研究空白。研究结果表明，么站断层埋深相对较浅，以左旋走滑为主，浅层地震勘探剖面显示为正断层，因未进行SEM、TL、OSL测年，暂时无法判断断层的最新活动时代，综合地质、遥感、浅勘数据，判断可能的最新活动时代为中更新世晚期—晚更新世早期（Q2—Q3）。
The Yadu-Ziyun fault zone is the most active fault zone in western Guizhou and has been active since Quaternary. Many studies have been made on the active age and geometric structure of the Yadu-Ziyun fault zone, but most of them focus on the exposed fault zone, and there is no research on the hidden fault zone. This paper mainly uses field geological survey, shallow seismic exploration, borehole combined geological section, and other deep, shallow, and surface three-dimensional multi-level research methods to analyze the geometric characteristics of the Yadu-Ziyun fault zone and the relationship between deep, shallow, and surface structures, so as to fill the research gap in the activity characteristics of the hidden area of the Yaozhai fault zone in the Yadu-Ziyun fault zone. The research results show that the buried depth of the Yaozhai fault is relatively shallow, the fault characteristics are mainly left-lateral strike-slip, and the shallow seismic exploration section shows that the fault is a normal fault. However, due to the lack of SEM, TL, and OSL dating, the latest activity age of the fault cannot be judged temporarily. However, according to the comprehensive geological, remote sensing, and shallow survey data, the probable latest activity age is the late Middle Pleistocene-early late Pleistocene (Q2-Q3).
