本文研究了沉积岩、泥火山及喷出火山中天然气的氦同位素成份。查明了在天然气中 He~3/He~4有广泛的变动范围——10~(-10)—10~(-5),分析了地球深部 He~3及He~4性状的个别规律性。其中查明了在天然气成份中He~3和 He~4浓度之间的线性依赖关系——主要是证明He~3的核物理的来源,以及查明了地层分异:比值较低的是古地台气体的特征;比值较高的是海西后地台年青沉积,特别是深拗陷区的特征。根据喷出火山和陨石的氦同位素成份相近这一点得出结论,认为在地球深部保存有原始的氦。
This paper studies the helium isotope composition of sedimentary rocks, mud volcanoes and natural gas emitted from volcanoes. It is found that He ~ 3 / He ~ 4 has a wide variation range of 10 ~ (-10) -10 ~ (-5) in natural gas and the individual regularity of He ~ 3 and He ~ 4 in deep earth . The linear dependence between the concentrations of He ~ 3 and He ~ 4 in natural gas was ascertained - mainly to prove the origin of He ~ 3 nuclear physics and to identify stratigraphic differences: The characteristics of the gas on the platform; the higher the ratio is the characteristics of the young sediments on the platform after the Hercynian, especially the deep depression area. The conclusion based on the similar helium isotope composition of volcanic eruptions and meteorites suggests that primitive helium is preserved deep in the earth.
