The petrochemical category of various diagram gave contradict results between alkaline and tholeiitic series. The rare earth elements show patterns from slight depletion to slight edrichment of ligh REE,showing the transitional features of MoRB and IAT, which is consistent with lower...             云南龙脖河铜矿区浅变质火山岩、辉绿岩与火山碎屑岩均具明显富钠贫钾特征；从各种岩石化学分类图解可得到互相不同的判别结果。轻稀上从略富集到略亏损的分配模式及低的RB、Sr含量表明具从洋中脊至岛弧拉斑玄武岩过渡的特征。各种火山岩TiO2与Nb、Th、Y、重稀土元素之间存在好的正相关关系，稀土模式具平移的特征均表明存在强的钠交代细碧岩化作用。钠交代作用与铁矿化同时发生。上述地球化学特征和大红山群变钠质火山岩系相一致。 文摘来源          Nd-Sr-Pb isotopic data indicate that the sodium enriched volcanic rocks from the Longbohe copper deposit Jinping, Yunnan Province, SW Chin4 were erupted during Proterozoic. The Pb-Pb isochron from the fresh soditum enriched volcanic rocks yields an age of (1596±140) Ma, which is interpreted as the formation age of volcanic rocks and is in agreement with the age of the Dahongshan Group (1660 Ma) within analytical errors. Sm-Nd isotopic systematics give an isochom age of (1330±150) Ma with ,...             多种同位素方法定年结果证实了云南金平龙脖河铜矿区变钠质火山岩系形成于元古古。（1596±140）Ma的Pb-Pb等时年龄表明其形成时代应与大红山群变钠质火山岩相当，属中元古代。（1330±150）Ma的Sm－Nd等时年龄应代表了这套火山岩发生钠交代细碧岩化作用的时间，与哀牢山岩群和瑶山岩群的大理岩沉积时间相近。火山岩的Rb-Sr年龄和铜矿石的Pb-Pb年龄记录了晋宁期强烈的动力变质和铜的强力改造成矿事件。该区变钠质火山岩系与大红山群变钠质火山岩系在形成时代、岩石组合、同位素体系特征以及改造成矿时代上的相似性，使该区成为寻找大红山式钢铁矿床的极有利地区。 文摘来源       相关查询: sodium (sodium enriched sodium enriched volcanic rock sodium enriched volcanic rocks glutamate sodium sodium rhodanide sodium vapour enriched mantle sodium acrylate pentachlorophenol sodium sodium tripolyphosphate  对查询结果不满意
