摘要: 东昆仑造山带志留纪的岩浆岩对于确定原特提斯洋的碰撞演化过程具有重要意义.通过对东昆仑造山带东段沟里地区出露的迈龙二长花岗岩及花岗闪长岩开展岩相学、年代学、地球化学和锆石Hf同位素研究，探讨岩石成因及其形成的构造背景.结果表明，二长花岗岩和花岗闪长岩年龄分别为438±3 Ma和426±2 Ma，指示侵位时代为早志留世和晚志留世.二长花岗岩具有高硅（SiO2=71.86%~74.37%）、富钾（K2O=4.67%~5.81%）、贫钙、镁、钛和磷和弱过铝质（A/CNK=1.01~1.08），较富集大离子亲石元素（K、Rb、Sr、U和Th），亏损高场强元素（HFSE，如Nb、Ta和Ti）等特征，以及负Eu异常特征，锆石εHf（t）值在-9.2~12.7之间，二阶段模式年龄T2DM（Hf）为1 805~592 Ma.花岗闪长岩具有高铝（Al2O3=15.90%~17.12%）、高锶（Sr=359×10-6~468×10-6）、低钇、高Sr/Y（33.2~87.5）和（La/Yb）N（11.6~43.7）比值等特征.岩石稀土元素总量较低，轻重稀土分异明显，富集大离子亲石元素（LILE；Rb、K、Sr、Th、U），亏损Ba、Nb、Ta、P、Ti等元素，具有正Eu异常特征，锆石εHf（t）为-4.9~-0.7，二阶段模式年龄T2DM（Hf）为1 559~1 322 Ma.迈龙二长花岗岩具有高分异I型花岗岩的特征，是下地壳长英质岩浆和少量地幔镁铁质岩浆混合后经历高程度分离结晶作用的产物；与前者不同的是，花岗闪长岩具有埃达克岩的特征，由加厚的新生下地壳部分熔融后经过一定程度分离结晶作用形成.结合区域上报道的最新资料，二长花岗岩和花岗闪长岩可能分别形成于同碰撞环境和同碰撞向后碰撞伸展的转换环境.东昆仑地区至少在早志留世（440 Ma）开始进入同碰撞阶段，经历一个快速大陆碰撞期（440~427 Ma），并在427~425 Ma之间由于板片断离而由碰撞阶段向后碰撞伸展阶段转换.Abstract: The Silurian magmatic rocks of the East Kunlun Orogen are of great significance in determining the collisional evolution process of the proto-Tethys Ocean. In this study, the petrographic, chronological, geochemical and Hf isotope analysis were carried out for Mailong granodiorite and monzogranite exposed in the Gouli area of the eastern section of the East Kunlun orogenic belt, and the rock genesis and formation were discussed accordingly construction background. The results show that the zircon weighted mean ages of Mailong monzonite and granodiorite are 438±3 Ma and 426±2 Ma, which indicated it was formed in Early Silurian and Late Silurian. The granodiorite is characterized by high silic, enrichment of alkaline, but depletion in calcium, magnesium, titanium and phosphorus. The A/CNK values range from 1.01 to 1.08.The rock is obviously enriched in large ion lithophile elements (LILE; K, Rb, Sr, U, Th etc.) and depleted in high field strength elements (HFSE; Nb, Ta, Ti etc.), with negative Eu anomalies. The zircon εHf (t) value has a wide range (from -3.54 to -0.56), and the two-stage mode age T2DM (Hf) is 1 805 to 592 Ma. The granodiorite is characterized by high aluminum, high strontium content, high Sr/Y and (La/Yb)N ratio and lower yttrium content. The total amount of rare earth elements in the rock is low, the differentiation between light and heavy rare earth elements is obvious, with positive Eu anomaly characteristics. εHf(t) ranges from -4.9 to -0.7, and the two-stage model age T2DM (Hf) is 1 559 to 1 332 Ma. The monzonite showing characteristics of highly fractionated I-type granites, it is formed by a high degree of separation and crystallization after the mixing of felsic magma in the lower crust and mafic magma in the mantle. But the granodiorite has the characteristics of adakite, it is formed by subsequent crystallization after partial melting of the thickened juvenile lower crust. Combining with new regional studies, the monzonite and granodiorite may have been formed in a syn-collision environment and a transition environment from syn-collision to post-collision extension. It proposes that the East Kunlun area began to enter the syn-collision stage at least in the Early Silurian (440 Ma), experiencing a period of rapid continental collision (440-427 Ma), and due to slab break-off began to transform from the syn-collision stage to the post-collision extension stage between 427 to 425 Ma.
