珠江口盆地位于珠江河口外。断块掀斜构造是指被断裂围限或切割的断块,在应力场由挤压变为引张的条件下,由于控制断块的主要断裂性质的变化,导致断块一侧掀起,另一侧倾斜的构造。这种构造在珠江口盆地中非常发育。它对珠江口盆地的形成和发育,对油气的生成与赋存起着重要的作用。因此,研究断块掀斜构造对珠江口地堑的形成和演化,沉积建造和沉积的迁移规律,沉积矿产(主要是石油)的形成和分布都有重要的意义。
Pearl River Mouth Basin is located outside the Pearl River estuary. Fault block tilt structure refers to the fault truncated or cut the block, the stress field from the extrusion into tension under the conditions of the main faults due to the control of changes in the nature of the fault block, causing one side off the block, and the other Slanted structure on one side. This structure is very developed in the Pearl River Mouth Basin. It plays an important role in the formation and development of the Pearl River Mouth Basin and the generation and occurrence of oil and gas. Therefore, it is of great significance to study the formation and evolution of the graben in the Pearl River Mouth, the migration of sedimentary structures and sediments, and the formation and distribution of sedimentary minerals (mainly petroleum).
