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。
The Cenozoic tectonic events in the northeastern South China Sea and its adjacent areas are mainly from the end of the Cretaceous to the Early Paleocene to the middle of the Eocene, from the Late Eocene to Early Oligocene, from the Late Miocene to Pliocene The last five events occurred in the mid-Pleistocene. They perform well in the area with unconformities, loss of stratigraphy and magmatic activity, fractures and folds. In the same tectonic event, the time of occurrence of different tectonic units may be earlier and later, with a degree of strength and weakness. The nature of the tectonic event may be subject to tension, or land-based orogenicity, or the creation of a sea. However, these manifestations are interdependent and may occur in the whole region Tracking comparison.
