德国大陆科学钻探的地壳流体研究

STUDY OF CRUSTAL FLUID IN THE GERMANY CONTINENTAL SCIENTIFIC DEEP DRILLING PROGRAM

简要地介绍了德国大陆科学钻探过程中地壳流体的研究成果，以及与流体研究相关的某些问题。德国两个大陆科学钻孔提供了可达９１０１ｍ深结晶基底中古流体和现代流体样品，以及它们留在矿物和岩石化学、同位素成分上的指纹。据此，可以再造地壳流体的时空分布、化学成分、迁移途径、源区和演化过程。

In this paper,the research achievement of crustal fluid in the program (KTB) and some problems related to the fluid studies are briefly introduced.The two Germany Continental Deep Drilling Program (KTB) boreholes provide samples for studies of paleofluids (fluid inclusions) and free fluid of the crystalling basement,and their fingerprints on the chemical and isotopic composition of minerals and rocks reach to 9 101 m depth,which may be used to reconstruct of the spacetime distribution and evolution of fluid,their migration pathways,and sources.
