【摘要】 选用仪器中子活化法测定了新疆西准噶尔洪古勒楞蛇绿岩中玄武岩的稀土元素(REE)、过渡金属微量元素和不相容微量元素。地球化学研究认为,洪古勒楞玄武岩有两组:第一组与洪古勒楞蛇绿岩体有成因关系,包括部分辉绿岩和粗玄岩;第二组为与洪古勒楞蛇绿岩体无成因关系的洪古勒楞围岩玄武岩。探讨这两类玄武岩的成因联系,对与蛇绿岩有关各种岩石的成因类型、源区特征、相互联系、演化过程和含矿规律等的深入研究具有重要意义。更多还原

【Abstract】 The REE and trace elements contents in the basalt of the west Zhunger Hongguleleng ophiolite have been measured with INAA method. The geochemical characteristics have been analyzed according to the amounts of its rare earth elements, transition metal trace elements and incompatible elements. The Hongguleleng basalt could be di- vided into two groups: one mainly consists of the basalt which is correlative with the formation of the Hongguleleng ophiolite, including some diabase and trachybasalt, while the other mainly consists of the wall rock basalt which is not correlative with the formation of the Hongguleleng ophiolite. It is significant to research this two types of basalt for studying their formation class, origin characteristics, relative dependence, evolvement procedure and the rule of coming into mine.更多还原
