| 摘 要： | 珠江口盆地东部和台湾西部海域广泛分布的海相中生界发育 3个方向的 4种断层 :NE向逆断层、NE向正断层、WNW—EW向正断层和NW向左行平移断层。区内各构造单元之间的接界关系有所不同 ,珠一坳陷、台西南盆地与隆起均呈断裂接界关系 ,潮汕坳陷与东沙隆起之间为渐变过渡关系 ,而东沙隆起与澎湖北港隆起、潮汕坳陷与台西南盆地均以平移断层为界。本区中、新生代构造演化主要表现为两次大的构造沉降与挤压隆升的旋回

| Abstract: | Four types of faults trending in three directions have developed in marine Mesozoic of the eastern Pearl River Mouth basin and offshore western Taiwan, including NE?trending reverse faults, NE?trending normal faults, WNW-EW?trending normal faults and NW?trending sinistral strike_slip faults. The junctures between various tectonic elements are different. Both Zhu I depression and Southwest Taiwan Basin border the uplifts by faults, and there is a gradual transition zone between Chaoshan depression and Dongsha uplift. In addition, there are strike_slip faults as juncture boundaries between Dongsha uplift and Penghu?Beigang uplift and between Chaoshan depression and Southwest Taiwan basin. Mesozoic and Cenozoic tectonic evolution is mainly composed of two major cycles of subsidence and uplifting in the study area. |
