DIVISION AND CHARACTERISTICS OF TECTONIC UNITS OF THE EAST CHINA SEA SHELF BASIN
-
摘要: 东海陆架盆地的构造单元存在多种划分方案,其分歧在于东西分带还是南北分块为主。通过对盆地全区大量地震剖面和重磁资料的解释与分析,并结合前人的研究成果,以地层分布和盆地结构特征为原则,强调"早期南北分块、晚期东西分带"的观点,将盆地自西向东划分为:(1)西部坳陷带,包括长江坳陷、台北坳陷、彭佳屿坳陷;(2)中央隆起带,包括虎皮礁隆起、海礁隆起、渔山隆起和福州隆起;(3)东部坳陷带,又称浙东坳陷。这一划分方案体现了盆地内新生代沉积地层的分布及厚度变化、地质结构、构造演化等方面的特征,这对于认识全盆结构、对比东西差异及区域油气勘探都具有指导意义。Abstract: Due to the different understanding of the geological architecture of the East China Sea Shelf Basin characterized by "east-west zonation or north-south blocking", there are debates on the division of tectonic units. Based on the study of seismic lines combined with gravity and magnetic data in addition to previous research, taking the sratigraphic distribution and basin architectures as the key, the authors divided the East China Sea Shelf Basin into three parts:(1) the West Depression Belt, which includes the Changjiang, Taibei and Pengjiayu depressions; (2) the Middle Uplift Belt, which includes the Hupijiao, Haijiao, Yushan and Fuzhou uplifts; and (3) the East Depression Belt or the Zhedong Depression. This division scheme has advantages to display the distribution and thickness variation of the Cenozoic deposits, basin architectures, and tectonic evolution, and is significant for overall understanding of the geology of the basin and the east-west differentiation. The division is also helpful in regional hydrocarbon exploration.
