高分辨率浅层地震勘探在探测隐伏断层中的应用
APPLICATION OF HIGH RESOLUSION SHALLOW SEISMIC PROSPECTING TO DETECTING HIDDEN FAULT
【摘要】 通过对河北省滦南县22万伏变电站厂址隐伏断层的探测,给出了采用高分辨率浅层地震勘探探测活动断裂的观测与解释方法,并给出了在县城南存在一规模较大的一组从第四纪Q_2地层一直断至太古界基底。它从属宁河—昌黎断裂的分支系列。断层附近存在第四纪隐伏玄武岩。
【Abstract】 Based on prosrecting hidden fault for the substation of 22 ten thousand volt inLan Nan County,He Bei province,we have given the method of observation and interpreta-tion method to apply shallow seismic prospecting with high resolution to detecting activefault.The results show that there is a set oflarger fault which is faulted from Quaternoryperild to Archaeon Era in the south of Lan Nan County.The fault is a branch of Ning He-Chang Li fault,and there is hidden basalt of Qaua ternory near the fault.
