查询词典 natural gas

K, the parent element of 40Arr, has different abundance in coal and argillite, which can be used in analyzing the difference between 40Ar/36Ar values of natural gases produced from coal and argillite, and identifying the main gas source in coal source rocks. In this paper, the forming mechanism of 40Arr and its process of entering into gas pool are discussed, on the basis of which a method for identification of main gas source is developed.
