摘要: 报道了南秦岭勉略构造带三岔子地区田坝辉绿岩的LA-ICP-MS锆石U-Pb年龄、主量元素及微量元素研究成果,并讨论了研究区勉略构造带新元古代时期的构造演化。田坝辉绿岩LA-ICP-MS锆石U-Pb测年结果为(805.9±2.6)Ma(MSWD=0.033,n=9),限定其形成时代为新元古代中期。田坝辉绿岩属钙碱性系列,稀土元素配分曲线呈右倾型,Eu负异常不明显(δEu平均为0.91),微量元素配分曲线显示富集Rb、Ba、Sr等大离子亲石元素和轻稀土元素,亏损Nb、Ta等高场强元素,相对亏损P和Ti。综合研究表明,田坝辉绿岩具有陆缘弧岩浆岩的地球化学特征,为俯冲流体交代富集的岩石圈地幔在伸展构造环境下部分熔融的产物;结合前人研究,勉略构造带及其邻区在新元古代中期(800Ma左右)由区域性的汇聚环境向后碰撞-裂解环境转变。Abstract: This paper presents an analysis of LA-ICP-MS zircon U-Pb dating, major elements and trace elements of Tianba diabase in Sanchazi area of Mianlue tectonic belt,south Qinling. It discusses the tectonic evolution of the Mianlue tectonic belt in Neoproterozoic.The LA-ICP-MS zircon U-Pb dating is (805.9±2.6) Ma(MSWD=0.033,n=9), indicative of a middle Neoproterozoic formation age.The geochemical data show that the Tianba diabase belongs to the calc-alkaline series.The REE pattern shows enrichment of LREE; The REE patterns show rightward incline.Eu negative anomaly is not obvious(the average δEu is 0.91).The trace elements pattern shows enrichment in LILEs(Rb, Ba, Sr,etc), and LREEs, and depletion of HFSEs (Nb, Ta),relatively depletion of P and Ti.Comprehensive study indicates that Tianba diabase has the geochemical characteristics of continental marginal magmatic rocks,which was formed by partial melting of the subduction fluid metasomatised enriched lithospheric mantle in an extensional setting. Mianlue tectonic zone and its adjacent areas was from regional convergent environment to postcollision-cracking environment in the middle Neoproterozoic (about 800 Ma).
