福建沿海中生代变质带,是我国东南部濒西太平洋的欧亚大陆前缘中生代近北东向线性构造变质带的一部分。它从福建沿海一直延伸到广东境内,通称为“长乐—南澳变质带”,长约500公里,宽约30—60公里。该变质带与广泛分布的中生代花岗岩、中酸性火山岩共生。其成因、形成条件、形成时代和原岩时代及其地质构造环境,早已引起地质界极大的兴趣,同时在这些问题上也产生一些分歧意见。为此,福建省地质局各地质队作了大量工作,特别是福建省区测队和长春地质学院等单位的研究成果,值得注意。
The Mesozoic metamorphic belt along the coast of Fujian Province is a part of the Mesozoic Neolithic metamorphic belt in the southeastern margin of the Eurasian continental margin in the western Pacific. It extends from the coast of Fujian Province to Guangdong Province, commonly known as “Changle - Nan’ao Modification Belt,” about 500 km long and 30-60 km wide. The metamorphic belt is widely distributed with Mesozoic granitoids and intermediate-acid volcanic rocks. Its causes, formation conditions, the formation of the times and the original rock age and its geological tectonic environment have already caused great interest in the geological community, and also have some disagreements on these issues. To this end, the Geological Bureau of Fujian Province geology team made a lot of work, especially in Fujian Province and Changchun Geological Survey teams units such as the research results, it is noteworthy.
