摘要
为深入研究长江中下游成矿带基底物质组成和早期构造演化特征,对安徽洪镇地区董岭杂岩中的一套正变质岩系中的黑云母二长片麻岩进行了LA-ICP-MS锆石U-Pb年代学和Lu-Hf同位素研究。结果表明,黑云母二长片麻岩形成于1840Ma,进一步证实长江中下游成矿带存在可靠的古元古代岩浆事件;样品具较低的ε_(Hf)(t)值(-7.2~-12.0),二阶段Hf模式年龄为2.93~3.27 Ga。结合区域研究成果认为,所研究的黑云母二长片麻岩与董岭杂岩中已发现的花岗质正片麻岩(1850 Ma)一样,可能都起源于太古代陆壳物质的再造,形成于与Columbia超大陆的裂解有关的板内伸展-拉张的构造环境,同时还可能参与了该成矿带中中生代的成岩成矿作用。
        In order to constrain the basement composition and Paleoproterozoic tectonic evolution of the middle-lower Yangtze metallogenic belt,orthometamorphite( biotite monzonitic gneiss) of the Dongling complex in Hongzhen area,Anhui province was performed zircon U-Pb and Hf isotopic analyses. LA-ICP-MS zircon U-Pb dating yields a ~(206)Pb/207 Pb age of 1. 84 Ga,indicative of the activity of Paleoproterozoic magmatism. Zircons from the gneisses have ε_(Hf)( t) values ranging from-7. 2 to-12. 0 and t_(DM2) model ages from 2. 93 to 3. 27 Ga. Combined with the results of previous studies,we suggest that the biotite monzonitic gneiss and granitic orthogneiss( 1850 Ma) of the Dongling complex were generated by the partial melting of Archean crust in an intraplate extensional setting,which might respond to the breakup of Columbia. In addition,the Precambrian basement has been the major source of widespread Mesozoic magmatism that has been responsible for large-scale Cu-Fe-Au mineralization in the middle-lower Yangtze metallogenic belt.
