摘要:
黑龙江省大兴安岭地区大面积分布的中基性火山岩的时代厘定对研究大兴安岭中生代火山岩带的构造演化及地层划分具有重要意义。本次基于开展的黑龙江省盘古林场幅、布鲁克里河幅1∶5万区域地质矿产调查项目，对该区原划为中—晚侏罗世塔木兰沟组的中基性火山岩进行了系统的LA-ICP-MS锆石U-Pb年代学、岩石学、岩石地球化学等方面研究。其中2件粗安岩年龄分别为(185.8±8.1)Ma、(196.8±2.1)Ma，玄武安山岩年龄为(196.3±2.7)Ma，时代为早侏罗世，表明在塔木兰沟组中存在一套早侏罗世中基性火山岩。通过岩石地球化学研究表明，该套中基性火山岩总体属于准铝质，以高钾钙碱性-钙碱性系列为主，显示富集Ba、K、La、Ce、Sr、Zr等大离子亲石元素和轻稀土元素，亏损Th、Nb、P、Zr、Ti等高场强元素和重稀土元素特征。认为该套早侏罗世中基性火山岩的形成与蒙古—鄂霍茨克洋板块向额尔古纳地块下的俯冲作用关系密切，构造环境为活动陆缘环境。
Abstract:Intermediate-basic volcanic rocks are largely distributed in Greater Khingan Mountains of Heilongjiang Province, and the determination of their ages is of great significance to understanding the regional tectonic evolution and petrogenesis of the Mesozoic volcanic belt in the Great Xing'an Range. Based on the 1:50000 regional geological and mineral resources survey in the study area, the LA-ICP-MS zircon U-Pb geochronology, petrology and petrogeochemistry of the intermediate-basic volcanic rocks previously attributed into the Middle-Late Jurassic Tamulangou Formation were systematically studied. Zircon U-Pb dating of the two trachyandesite samples and one basaltic andesite sample yields (185.8±8.1)Ma, (196.8±2.1)Ma and (196.3±2.7)Ma respectively, which indicates that there exists a set of early Jurassic intermediate-basic volcanic rocks in the Tamulangou Formation. These Early Jurassic volcanic rocks belong to metaluminous, mainly high-K calc-alkaline series generally enriched in large ion lithophile elements (such as Ba、K、La、Ce、Sr、Zr) and LREE, but depleted in high field strength elements (such as Th、Nb、P、Zr、Ti) and HREE. Combined with the regional tectonic evolution, it is conclude that the early Jurassic intermediate-basic volcanic rocks were formed in an active continental margin setting related to the southward subduction of the Mongol-Okhotsk oceanic plate beneath the Erguna Massif during the Early Jurassic.
