摘　　要： 在前人工作的基础上,通过收集石油部门的钻孔资料,依据桐柏断裂南北两侧的2条钻孔联合剖面,给出桐柏断裂周围第四系厚度分布图,图中显示桐柏断裂所在区域缺失早更新世地层,断裂北部的第四系厚度小于南部,表明桐柏断裂向南倾;同时利用廊坊城市活断层探测成果,根据跨桐柏断裂联合钻孔剖面、桐柏断裂详细勘探地震剖面和桐柏断裂附近的石油钻孔资料,综合判定桐柏断裂的活动时代,认为桐柏断裂最新活动至中更新世。 On the basis of existing works, using the complementary survey and collection of Oil drilling da-ta, according to two drilling joint section of Tongbai fault on either side of the north and south, the distri-bution map of quaternary thickness around Tongbai fault is given. The results show that the area around Tongbai fault missing early Pleistocene stratum, the Quaternary thickness in the north of Tongbai is less than that in the south, which indicates that Tongbai fault is dipping to the south. This article also uses the result of the Langfang city active fault detection combined with the result of borehole profile across the Tongbai fault, accurately survey seismic profiles of Tongbai fault and oil borehole data near the Tongbai fault to judge activity age of Tongbai fault. We can get the conclusions that the active age of Tongbai fault is to the latest Pleistocene.
