Abstract

Abstract

A variety of veins were discovered during the observation and identification of rocks from the main hole of CCSD (the China Continental Scientific Drilling Project), which is located at the eclogite area in North Jiangsu. These veins can be divided into four series:① related to the UHP/HP stage; ② related to the decompression and partial melting stage; ③ related to the retrograde metamorphism stage; ④ related to the late exhumation stage. Especially, large numbers of REE-mineral-rich veins were found at depths of 3578.5-4006m. These veins from the CCSD main hole were widely distributed and some were closely related to mineralization. In genesis, they may be the result of geological fluid metasomatism on a large scale.
