摘要：
2016年10月15日发生的地震（Ml=5.0）再次引起了人们对西黑海盆地构造活动的关注。这次地震的震源机制解表明，与1968年9月3日黑海土耳其边缘仪器记录到的最强地震--巴廷地震（MS=6.6）相似，为逆冲活动提供了又一地震学证据。利用海洋地震反射资料和综合测井资料，揭示了西黑海盆地南部Akcakoca-Cide近海陆架区和陆坡区受挤压构造体制影响形成的断裂构造及其活动形成的构造。通过以往地质研究中的地质剖面，制作了陆-海地质剖面，并介绍了研究区地质特征从陆到海的延续情况。这些地质剖面和地震偏移剖面的地质特征支持了西黑海存在南北向挤压构造体制。
英文摘要：
The earthquake occurred on October 15, 2016 (Ml=5.0) re-attracted attention to the tectonic activity of Western Black Sea Basin. The focal mechanism solution of this earthquake indicates reverse faulting, similar to the Bartin Earthquake of September 3, 1968 (MS=6.6), which is the strongest instrumentally recorded earthquake along the Turkish margin of Black Sea, and reveals another seismological evidence for the active thrusting in the region. In this study, the fault structures that considered to be formed by the effect of compressional tectonic regime and the structures formed by the activities of these faults beneath the shelf and slope areas between the region offshore Akcakoca-Cide at the southern part of the Western Black Sea Basin revealed by using marine seismic reflection data and the composite well log data. By means of the geological sections in previous geological studies, the land-offshore geological sections were prepared and findings about the continuation of the geological features from land to offshore in the study area were presented. These geological sections developed for the study area and the geological features recognized from the seismic migration sections, support the presence of the N-S directional compressional tectonic regime in Western Black Sea.
