台湾海峡滨海断裂带地质构造特征

Tectonic characteristics of the Binhai Fault Zone in Taiwan Strait

  • 摘要: 为深入研究滨海断裂带的地质构造特征,收集、整理了台湾海峡西部的地质、构造和地球物理等相关资料并进行综合分析和研究。结果显示:(1)牛山岛、兄弟屿、南澎列岛3个关键海岛上的地质和线性构造直接反映了滨海断裂带的产状、性质、分段分布及区域变化等特征;(2)台湾海峡西部存在3条主要断裂带,其中F1为滨海断裂带,属于浙闽隆起上隆中凹陷的西界控凹断裂,F2断裂带为浙闽隆起上隆中凹陷的东界控凹断裂,F3断裂带为台西盆地西界控盆断裂,3条断裂带及其内部发育的正断层组合整体组成了海峡西部断裂系,控制了台湾海峡西部区域隆、坳格局的形成;(3)滨海断裂带和海峡西部断裂系被4条NW向区域断裂带自北向南切割为5段,即平潭外海段、泉州外海段、厦门外海段、东山外海段和南澳外海段。

     

    Abstract: In order to further understand the geotectonic characteristics of the Binhai fault zone of the Taiwan Strait, geological, tectonic and geophysical data in the western Taiwan strait are collected and carefully studied. The results suggest that: (1) The geological features, in particular the linear pattern of the three key islands, the Niushan Island, the Brotherhood Island and the Nanpeng Islands, directly reflect the occurrence, nature, sectional distribution pattern and regional variation of the Binhai fault zone; (2) There are three major fault zones in the western Taiwan strait, of which F1, the Binhai fault zone, is a sag-controlling fault and the western boundary of a second-order sag on the Zhejiang-Fujian uplift, F2 a sag-controlling fault, and the eastern boundary of the sag mentioned above, and the F3 fault zone, a basin-controlling fault, the western boundary of the Taixi Basin. The three main fault zones and the normal faults inside the zones together constitute the Western Strait fault system, which controls the formation of the uplifts and sags in the western Taiwan Strait. (3) The Binhai fault zone and Western Strait fault system are cut into five segments by four NW-trending regional faults, i.e. the Pingtan offshore segment, the Quanzhou offshore segment, the Xiamen offshore segment, the Dongshan offshore segment and the Nanao offshore segment from north to south,.
