The samples were pressed using pyropgyllite as the pressure medium. The conductance cell for the experiments was made of Teflon and platinum metal was used as electrodes. The detailed method for setting up of sample has been reported.展开更多

The results show that the amphibolites and TTG gneisses have a similar age of ca. 2 700 Ma, which well agrees with zircon U Pb dating of previous studies. However, their ε Nd ( t ) are different, suggestive of possible dissimilarity in source composition.展开更多
