| Abstract | Barium is an important trace–element in silicate–rocks, especially in granitic rocks. The Ba/Rb ratio can be used to determine if a granitic rock formed from a highly evolved melt or not. As the atomic number (Z) of barium is high (Z = 56), we have to use the characteristic radiations of barium from the x-ray L spectrum. The available analytical lines are BaLα, BaLβ1,3, and BaLγ1. BaLα, BaLβ1,3 is overlapped by TiKα. BaLγ1 liable to interference from CeLα. BaLγ1 is weak. The availability of 100 kV x –ray generators makes it possible to use BaKα to determine barium in silicate–rocks. |
