3) mantle xenolith
地幔岩
1.
REE in fluidmelt inclusions of mantle xenolith from Changbaishan are measured directly by ICPMS.
当前对地幔流体的REE研究,主要是通过对比富CO2包裹体与贫CO2包裹体的地幔岩或地幔矿物的测试分析来间接获得信息。
2.

这说明同一地区地幔岩中裂隙硫化物和硫化物包裹体的成分存在某种继承关系 ,其硫化物成分与该地区地幔橄榄岩的来源深度 (或经历部分熔融时的深度 )有一定联
3.
The discovery of sulfide-melt inclusions in mantle xenoliths is of great significance in further understanding mantle depletion and enrichment, as well as ore-forming processes of mantle fluids.

4) upper mantle rock
上地幔岩
1.
In the former province, the upper mantle rocks consist of harzburgite and lherzolite, characterized by the concentration of mantle type elements (K T) and the smooth-weak enrichment type REE patterns; the ocean volcanic rocks are dominated by basic rocks of subalkaline and oceanic ridge type; lead isotopes are noted for 206Pb/ 204Pb<18.
前者上地幔岩有方辉橄榄岩和二辉橄榄岩 ,幔型元素 (KT)富集 ,REE呈平坦—弱富集型 ;大洋火山岩以基性岩、亚碱性、洋脊型为主 ;铅同位素2 0 6 Pb/2 0 4 Pb <18。
