摘要
利用在琼州海峡所采集的综合地质地球物理资料和围区地质资料,对该海峡的浅层单道剖面和高分辨率多道地震剖面进行了地震层序划分及地质解释,阐述了主要地震层序与界面的反射特征,以及浅部地层的岩性特征,并对琼州海峡上新世-第四纪的构造发展史及海峡成因作了初步分析,这对琼州海峡的环境保护及研究雷州半岛、海南岛区域地质有着极其重要的意义。
Based on geophysical prospecting data of the Qiongzhou Strait and geological data of the surround- ing area, shallow single-channel seismic profile and multi-channel seismic profile of high-resolution are interpreted and divided seismic sequence. The reflecting characters of main seismic sequence and in- terface , and rock characters of shallow stratum are expounded. History of tectonics development during Pliocene to Quaternary and the cause of formation about Qiongzhou Strait are initially analyzed. It is important to protect environment of Qiongzhou Strait and study the region geology of Leizhou Peninsula and HaiNan island.
