| 英文摘要 | The Dongjiazhuang and Xindian Plutons are emplaced in Proterozoic metamorphic rocks of the Central Qilian. LA-lCP MS zircon U-Pb data indicate that the emplaced ages of these two plutons are Paleozoic. The plutons are peraluminous, showing characteristics of high K and K/Na, and low Mg, Fe, and Ca. The rocks are enriched in Rb, Th, Pb, LREE and depleted in Ba, Nb, Sr, P, and Ti, with Eu positive anomaly. Their (Sr-87/Sr-86)(i) are respectively 0.7129 and 0.7106, and epsilon(Nd) (t) are - 6. 6 and - 5. 2. Based on these geoehemical characteristics, we conclude that the plutons are S-type granites whose source rocks were metagreywacke, and their tectonic settings belong to syn-collision. |
