Abstract

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.
- mantle derived minerals,
- step heating,
- characters of degassing,
- Yishu fracture zone
