| Abstract: | Among the high grade metamorphic rocks of Taipingzhai,two types of basic granulites and their retrograded amphibolites can be recognized.According to the REE abundances and patterns,one type probably belongs to continental basalt and the other to alkaline basalt,of which the BEE content is up to 400 ppm,apparently riched in LREE.The coexistence of two types of the basalts implies the exsistence of an old continental rift structure. |
