| 英文摘要 | A detailed investigation of mineralogy and petrology on amphiboles demonstrates that the granulite terrane of Yushugou underwent a four-stage metamorphism, i.e., high-pressure granulite facies, medium-pressure granulite facies, amphibolite facies and greenschist facies. The sequence and the features of the metamorphism in each stage are concluded in the paper. The Ar-40-Ar-39 dating obtains a plateau age of 368. 2 +/- 4. 8Ma and an isochron age of 360 +/- 10Ma. The Sm-Nd mineral-rock isotopic dating gets an isochron age of 310 +/- 5Ma by using Gra + PI + Ilm + whole rock assemblage. Based on the dating results in this paper and literatures, the Ar-40-Ar-39 age is probably the peak-stage age of high-pressure granulite facies of Yushugou terrane while the Sm-Nd age is a retrograde age of medium-pressure granulite facies. The homogenization and block temperatures of isotopes in the multiple-stage metamorphism are also mentioned in the paper. |
