福建沿海中生代变质带位于我国东海之滨,呈北东方向狭长条带与海岸线平行展布,大致与长乐——南澳深大断裂带展布方向一致,长约400余公里,宽仅38—58公里。它是由一套中生代晚三叠—晚侏罗世的沉积—火山岩系经区域变质作用、混合岩化作用形成的,其变质时代大致相当于晚侏罗—早白垩世,是一条年青的区域变质带。
The Mesozoic metamorphic belt along the coast of Fujian Province is located in the coast of China’s East China Sea. Its northeast direction is parallel to the coastline. The Mesozoic metamorphism belt is roughly consistent with the distribution direction of the Changle-Nan’ao deep fault zone. It is about 400 km long and has a width of only 38-58 Km. It is formed by a set of Mesozoic Late Triassic-Late Jurassic sedimentary-volcanic series formed by regional metamorphism and mixed lithification. Its metamorphic age roughly corresponds to Late Jurassic-Early Cretaceous and is a young region Metamorphic belt.
