| 英文摘要 | A suite of alkali-rich porphyry with 26.5-37. 6Ma occur along the Jinsha River suture zone in west Yunnan. They are characterized by LREE-rich distribution patterns and no Eu anomaly. These porphyries have formed in post-collisional environment; (Sr-87/Sr-86)(i) Of porphyries, amphibolite xenolithes and associated basalts are 0.707 3, 0.706 5-0.707 1 and 0.705 8-0.706 5, epsilon(Nd)( T) are -3.4- - 6.3, - 2.1- - 7.4 and - 3.3 respectively. Pb isotope compositions of these rocks also show a little difference; The evidence shows that the porphyry could be derived from partial melting of the "crust-mantle mixed layer". The relation between Cenozoic magmatism and intraplate deformation since Paleogene has been discussed. |
