摘要:
在地质调查与盆地区浅层人工地震初步勘探基础上,在西秦岭北缘断裂带漳县盆地隐伏段的盆地内布设了3条浅层人工地震详勘测线,用于精确定位该断层的空间展布,判定其浅地表活动特征。在此基础上,用钻孔联合剖面方法对人工地震探测结果进行验证,同时确定了各地震测线处断层上断点的位置和埋深,通过钻孔揭露断层错断地层的特点,认为西秦岭北缘断裂漳县盆地隐伏段错断全新统,指示该断层全新世以来活动性较强。

Abstract:
Based on geological survey and preliminary exploration of shallow seismic in basin area,three detailed seismic lines are arranged to locate the spatial distribution and determine its shallow surface activity characteristics of buried segment of the fault zone along the north edge of western Qinling mountains in the Zhangxian basin. With the result as a reference,composite drilling sections accurately identify the location and depth of upper faulted point. The latest activity characteristics are analyzed in the paper.
