介于戴云山隆起带与台湾海峡沉降带之间的福建沿海长乐—诏安构造带,以断裂构造为主要构造型式,故通常称其为长乐—诏安断裂带。按断裂展布的方向主要可分为北北东—北东、北北西—北西、近东西向三组,此外尚有南北向及弧形断裂(帚状、环状)等零星分布。上述三组主要断裂相互交切,使本区地壳呈现出网络状的构造格局,
The Changle-Zhao’an structural belt along the coast of Taiwan between Dai Yunshan uplift and the Taiwan Strait subsidence zone is characterized by faulted structure as the main structural type, so it is often called Changle-Zhaoan fault zone. According to the direction of fault distribution can be divided into North-East-North East, North-West-North West, Near East-West three groups, in addition there are north-south and arc-shaped fracture (broom, ring) sporadic distribution. The three major faults intersect with each other to make the crust in this area show a network-like tectonic pattern,
