摘要
Many Quaternary folds and faults are identified on the seismic reflection profiles acquired in the adjacent areas of Qianliyan Island of southern Yellow Sea. The faults are mainly of reverse fault. The folds are mainly gentle and tilted, caused by fault activities. Most folds and faults occurred below a plane of unconformity between middle Pleistocene and its overlying upper Pleistocene. Some faults, such as Qianliyan fault, are late Pleistocene active fault. At that time, the N-S striking horizontal stress drove the early-developed basin boundary faults reactive and further induced the NEE or E-W striking tectonic deformation in the overlying sedimentary layer.
