  the mantle fluid
In response to low environmental salinity, all three species closed the opercular plates firmly and rapidly used up oxygen within the mantle fluid.
      
When isolated, the mussels maintain a high osmotic concentration in the mantle fluid as the external salinity drops.
      
We also observed that both 3H-protein and 3H-glycine concentrations were higher in the mantle fluid than in the external sea water, although the ratios of 3H-glycine to 3H-protein in these two fluids were not different.
      


The results of study on the middle-pleistocene basanites and the mantle-derived lherzolite xenoliths entrained by the formers from Nushan indicate that the volatils dissolved in high-pressure solid mineral phases of mantle peridotite at mantle depth might be exsolved under the decompressive conditions at welling of asthenospheric mantle plume during preliminary continental rifting. These exsolvedly initial free fluid phases, which mainly consist of CO2, CO, H2O and small amounts...

The results of study on the middle-pleistocene basanites and the mantle-derived lherzolite xenoliths entrained by the formers from Nushan indicate that the volatils dissolved in high-pressure solid mineral phases of mantle peridotite at mantle depth might be exsolved under the decompressive conditions at welling of asthenospheric mantle plume during preliminary continental rifting. These exsolvedly initial free fluid phases, which mainly consist of CO2, CO, H2O and small amounts of N2, SO2, H2S, CH4, H2, Cl2 and F, accumulate in some regions of mantle, and they resulted in lowring of mantle solidus (and liquidus ) and might initiate partial melting in the upper mantle. The mantle fluids and the melts produced by partial melting of mantle peridotites under inducement of the formers would be highly enriched in incompatible elements. Interaction between them and depleted mantle could bring the latter about substantial local enrichments of LREE and incompatible elements. namely resulted in mantle metasomatic effect. The authors' studies reveal that the mantle metasomatism and partial melting had been synchronized under the Inducement of initial mantle fluids before 30 Ma and below the 37km depth within the mantle peridotites beneath Nushan. and the primary basanitic magmas, which would have the eutectic composition for mantle lherzolite system, would be simultaneously generated. The latters, segregated from their source region, ascended more rapidly and they might not undergo storage in high-level magma chamber within the crust and neither undergo contamination processes of the continental crust. The primary mantle-derived basanitic magmas might only undergo a modification to some extent during transport to the surface. being accompanied by a slight crystal fractionation

产于大陆板内环境的女山中更新世碧玄质火山岩及其所含幔源二辉橄榄岩捕虏体的研究结果揭示,在裂谷作用初始阶段,由于软流圈地幔柱上隆减压,造成深部溶解于地幔橄榄岩高压固体矿物相中的挥发组分出溶,这些出溶的初始地幔流体相在一定部位聚集,于30Ma前,大约37km之下,在地幔橄榄岩中诱发同步的部分熔融和交代作用,并相应产生原生碧玄质岩浆。后者上升速度较快,既未经历壳内高位岩浆房贮集,也没有遭受大陆地壳混染,只是在输送往地表的途中伴随结晶分离作用,发生一定程度演化。

The impure components captured in diamond can provide abundent information for the study of mantle fluid. The genesis of diamond, the solid inclusion indicating mantle fluid, the fluid inclusion and the restrictive factors of fluid are studied in this paper. The relationship between the impure component within diamond and the mantle fluid is also discussed.

Generally,the activity of various fluids in Earth’s interior has been commonly consid-ered as the fundamental condition for the mineralization and metallogeny.With the ad- vance in Earth sciences,the mantle fluid has been attracted attention for its special func-tion.Recent years a mantle fluid replacement ore deposit in China was discovered by theauthors. The Bayan Obo in Inner Mongolia,northern China is the world’s largest known rareearth elements(REE)ore deposit.In view of the overall low Sr isotopic ratios of REEminerals,the metallogenetic elements,REE and Nb etc. are thought to be derived frommantle source and a large involvement of older crustal material can be ruled out.The car-bon and oxygen within the REE fluocarbonate minerals are composed of mantle C and O;meanwhile,the surphur in the associated surphides belong to the meteorite S,according totheir isotopic composition. It is suggested that the REE ore- forming solution was not thehydrothermal brine from crustal source,but would be the mantle fluid that has never beendocumented in the classical works of economic geology and traditional metallogeny. Hence,it might be a unique mantle fluid metasomatic REE ore deposit in the world. In this paper,the basic problems on the mantle fluid and related metallogeny havebeen summarized.

地球内部流体的活动乃是形成各种矿床的必要条件,是导致矿物聚积和金属成矿作用的前提。随着地球科学的进展,作为地球内部流体的重要组成部分,地幔流体受到越来越多的重视。本文在解剖世界首例白云鄂博地幔流体交代稀土矿床的基础上,初步总结了地幔流体与成矿作用的基本问题。
