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
【摘要】 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。
【Abstract】 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.
