Large amount of bitumen and hydrocarbon-bearing organic inclusions were recognized in quartz veins in HP-UHP metamorphic rocks from Chinese Continental Scientific Drilling(CCSD)and Donghai crystals by observation under fluoroscope and determination with Laser Raman and infrared spectroscopy,reconfirming that the Dabie-Sulu UHPM belt undergone rapid subduction and exhumation,thus the organic materials in the sediments in the subducted slab were not highly matured and transformed to kerogen or graphite.The hydrocarbon-bearing fluids were released during dehydration and prograde metamorphism,and were captured by quartz veins or crystals,which were deposited during plate exhumation and the subsequent pressure decline and retrograde metamorphism.
