    大兴安岭北段中生代火山岩形成的动力学环境

    THE DYNAMIC BACKGROUND OF MESOZOIC VOLCANIC ACTIVITY IN NORTHERN PART OF DAXING' ANLING MOUNTAINS

      摘要
    • 摘要: 对大兴安岭北段中生代火山岩新的岩石化学、微量元素、构造等方面的分析表明，该地区中生代火山岩形成于明显的挤压环境.再结合区域构造、区域岩浆作用、稳定同位素、古地磁特征等的分析，得出以下认识：该区中生代火山岩来源较深，具幔源特征；岩浆总体形成在挤压的环境中，是"减压"-"剪切"作用的产物，而不是裂谷环境中的产物，从而使得岩浆在演化过程中混入了大量的壳源物质

       

      Abstract: The Mesozoic volcanic activity in northern Daxing'anling Mts.(NDM) is very violent,in which a lot of geologists are interested The volcanic rocks,formed mainly in Late Jurassic to Early Cretaceous(150~100 Ma),are divided into the Tamulangou formation(J3t),Jixiangfeng formation(J3j),Shangkuli formation(K1s) and Yilikede formation(K1y).
