摘要
南海东北部及其邻区新生代构造事件主要有白垩纪末—古新世早期、始新世中期、始新世晚期—早渐新世、中新世晚期—上新世初和上新世末—更新世中期发生的５次事件。它们在区内表现明显，伴有不整合、地层缺失和岩浆、断裂、褶皱等活动。同一构造事件在不同构造单元发生的时间可以有早有晚、程度有强有弱、性质有张有压，或造陆造山、或造海造盆，但是这些表现却互有联系且可在全区追踪对比。
suring the Cenozoic Era in the northeast area of South China Sea and its neighboring regions, there are five tectonic events which took place in Late Cretaceous-Early Paleocene, Early Eocene, Late Eocene-Early Oligocene,Late Miocene-Early Pliocene,and Late Pliocene-Middle Pleistocene.They show obvious characteristics in the studied region, and also had unconformity,stratum break, magmation, faulting, folding, and so on. The same tectonic event in different tectonic units might take place .earlier or later in time, stronger or weaker in intensity, tension or compress in stress, epeirogeny-orogeny or generation of sea and basin in tectonism. But all these characteristics had relations with one another, and can be traced and compared in the studied area.
