斯堪的纳维亚加里东造山带塞维推复体斯瓦措贝肯片岩组和迪坎内斯片岩组同构造石榴石单个晶体的Rb-Sr 分析显示出有规律的差别。一组得到前寒武纪年龄谱,这与全岩分析所获得的结果一致;另一组得到加里东期年龄,与根据云母分析资料所获得的年龄相似。由此可见,石榴石包体模式中所反缺的构造事 The Rb-Sr analysis of a single crystal of the same-structure garnet from the Swarovski Beck schist group and the Di-Kannes schist group in the Caledonian orogenic belt in the Scandinavia shows a regular difference. One group obtained the Precambrian age spectrum, which was consistent with the results obtained by the whole-rock analysis; the other group obtained the Caledonian age similar to the age obtained from mica analysis data. This shows that garnet inclusions in the pattern of the lack of construction
