摘要: 在综合分析区内重、磁、石油物探等资料的基础上,采用化探(气氡、气汞法)定位,浅层地震勘探、钻探地质剖面和新地层测年等综合研究,确定了聊城-兰考(简称聊考)隐伏断裂的准确位置、第四纪各时段位错量和最新一期的断错时代。结果表明,断裂向上破裂位错影响到地表以下20m左右,属全新世早期活动断裂,其平均位错速率为0.12mm/a。

Abstract: We have conducted an integrated survey and investigation on the Quaternary activity of the Liaocheng-Lankao buried fault. The used methods include geochemical exploration, shallow seismic exploration, drilling geological profile and neo-strata dating. The object is to determine the accurate location of the fault, dislocation amount of each time period since Quaternary and the offset age of the last time of dislocation. The results show that the dislocation of the fault extends upward to the depth 20m or so below the surface. This fault has been active in early Holocene time. The average slip rate of the fault is 0.12mm/a.

Key words: Liaocheng-Lankao buried fault, Quaternery activity, Integrated survey and investigation
