摘      要：Subduction is an important process for transferring materials from the surface into the deep *** subduction,recycled carbon can be released from the subducting slab to the mantle wedge through various decarbonation *** oxidized(CO2/CO32-) and reduced(CH4) carbon-bearing species have been discovered in(ultra)high-pressure(HP-UHP) subduction zones worldwide [1-3].Diamond is a typical index mineral for UHP metamorphism.
