用于地质研究和地震监测的稀有气体质谱分析法

Rare Gas Isotope Mass Spectrometric Method for Geology Research and Earthquake Monitor

利用自行研制的NG-1000型和NG-2型稀有气体同位素比值质谱计测得3He／4He、4He／（20）Ne、4He／（40）Ar和（40）Ar／（36）Ar的比值用于地质研究和地震监测。测定了西藏羊八井地热区和长白山天池火山区的3He／4He和4He／（20）Ne比值，研究了这些地区逸出稀有气体的来源，连续监测了北京塔院断层土壤气4He／（20）Ne、4He／（40）Ar和（40）Ar／（36）Ar比值，并进行了地震预报的探索，获得了一些震例。

The measuring method of rare gas isotope raios using the mass spectrometers developed by author for geology research and earthquake monitor is reported in the paper. We have measured 3He/4He and 4He/(20)Ne in Tibet Yangbajing Subterranean field and Changbaishan volcano field. The source of escaped rare gas in the two fields is researched. In addition, the continuouse monitor of 4He/(20) Ne. 4He/(40) Ar and (40)Ar/(36)Ar ratios in Taryun soil gas is carried out in order to study earthquake forecast. Some earthquake examples are obtained.
