  • It is very important to study the mantle fluids for understanding deep geologic processes within the earth. There are following rules for degassing of mantle fluids by step-heating for the mantle xenoliths of Shandong province: ①the degassing characters of primary mantle fluid components are different and they are: the degassing peak value for CH 4 are always at 500℃, and while more H2 were degassed with higher temperature as less CO2 were released;②three type fluids degassed in different temperature stage, such as 350~500℃,650~800℃ and 950~1100℃, implying different evolving stage fluids, were recognized.
