摘要/Abstract

摘要： 五女峰岩体位于通化地区集安市，大地构造位置上处于鸭绿江—图们江断裂北侧，其岩性为碱长花岗岩。为确定其侵位时代和探讨大地构造环境，对五女峰岩体进行了系统的岩石学、矿物学和年代学研究。LA-ICP-MS锆石U-Pb测年结果显示，其加权平均年龄为（110.50±1.60） Ma，侵位时代为早白垩世晚期。岩体具有高硅、富碱、富铝和低钛的特点，属于高钾钙碱性系列；A/CNK值为0.98~1.00，为准过铝质岩石；固结指数（I_S）为0.80~3.20，反映了该岩体经历了高程度分异演化作用；δEu为0.05~0.37，具较强的Eu亏损，LREE/HREE和（La/Yb）_N值分别为7.13~24.68和7.01~39.20，显示轻重稀土元素分馏明显，且具有轻稀土元素富集、重稀土元素亏损的特点。五女峰岩体呈现明显富集大离子亲石元素（LILE） Rb、K、Th、U，略富集高场强元素（HFSE） Nd、Sm、Zr、Hf，以及明显亏损P和Ti的特征。综合岩石矿物学、年代学、岩石地球化学特征及区域地质资料，五女峰岩体属于A型花岗岩，形成于后造山的伸展体制环境下。

Abstract: The Wunüfeng pluton is composed of alkaline granites,which is tectonically located at the NW Yalujiang fault in Ji'an area, Tonghua region. To determine its intrusive age and tectonic environment, mineralogical, petrological,and geochronological characteristics,a research of the pluton was carried out. The LA-ICP-MS zircon U-Pb age of sample JWNF01 is (110.50±1.60)Ma, belong to the late Early Cretaceous. The pluton has high content of SiO₂, Na₂O+K₂O, Al₂O₃ and low content of TiO₂, and belongs to high-K Calc-alkaline series. The A/CNK values are 0.98-1.00, belong to meta-to weak peraluminous rocks. The solidification index (I_S) is 0.80-3.20, reflecting that the rocks experienced high differentiation. δEu is 0.05-0.37, strongly depleted of Eu, LREE/HREE and (La/Yb)_N values are 7.13-24.68 and 7.01-39.20 respectively, indicating that LREEs are enriched and HREEs are depleted, clear fractionation of LREE and HREE. Meanwhile, the Wunüfeng pluton is clearly rich in LILEs (e.g., Rb, K, Th, U), slightly rich in HFSEs (e.g., Nd, Sm, Zr, Hf),and poor in P, Ti. The mineralogy, geochronology, petrology,and regional geological information show that Wunüfeng pluton belongs to high-K Calc-alkaline A-type granite, which was formed in an extensional tectonic background during post-orogeny period.

Key words: alkaline granite, zircon U-Pb age, petrological geochemistry, Wunüfeng pluton, SE Jilin Province
