Use of 36Cl for the Characterization of Crustal Fluids from the KTB Project

9319605 Fehn该项目是首席调查员在德国KTB深井中测定流体中宇宙成因同位素的工作的延续。初步结果表明，从先导孔和主孔采集的水中的36个氯/氯比反映了这些同位素的地下生产。因此，这些结果可用于确定这些水域的停留时间和来源构成。首席调查员在初期资金不多的情况下取得了良好的进展，以证明利用氯同位素系统学来确定在KTB井中发现的深部流体的停留时间和来源的可行性。这一项目的结果应该有助于更好地了解地壳深部流体的流动、来源和停留时间。***

9319605 Fehn This project is a continuation of the Principal Investigator's work on the determination of cosmogenic isotopes in fluids from the KTB deep drill hole in Germany. Initial results suggest that 36 Cl/Cl ratios in waters collected from the pilot hole and from the main borehole reflect the subsurface production of these isotopes. The results can therefore be used for the determination of residence times and source formations of these waters. The Principal Investigator has made good progress with modest initial funding to demonstrate the feasibility of using the chlorine isotope systematics to determine the residence times and sources of deep fluids found in the KTB boreholes. The results of this project should lead to a much better understanding of fluid flow, origin, and residence time of deep crustal fluids. ***
