| 英文摘要 | The Cenozoic magmatic rocks of shoshonitic series in the eastern Qinghai-Tibet Plateau include potassic alkaline plutonic rocks, volcanic rocks, lamprophyres and acidic porphyries. Analytical results show that these different lithological rocks are extremely similar in Sr, Nd and Pb isotopic compositions with the range of 0.705 187-0.707 254 for Sr-87/Sr-86, 0.512 305-0.512 630 for Nd-143/Nd-144, 18.53-18.97 for Pb-206P/(204)pb, 15.51-15.72 for Pb-207/Pb-204 and 38.38-39.24 for Pb-208/Pb-204. They are isotopically similar to the EMII end-member. This indicates that mantle metasomatism must have taken place in their source region. The formation of these particular rocks is related to crustal thinning and mantle upwelling in a large-scale strike-slip and pull-apart fault zone at about 40 Ma in northern and eastern Qinghai-Tibet Plateau. |
