    河南省花岗岩的含金丰度

    GOLD ABUNDANCE OF GRANITES IN HENAN PROVINCE

    • 摘要: 本文测定和统计了河南省86个不同成因类型和规模的花岗岩体的含金丰度,其平均含量为1.156×10-9,低于地壳含金丰度的3-4倍。不同成因类型的花岗岩的含金量不同,以大岩体-小斑岩体-碱性花岗岩的顺序逐渐增高。本文还讨论了不同期次、不同岩相的花岗岩的含金量和岩体含金量与金矿化的关系。

       

      Abstract: A ststistic analysis of gold abundance of 86 granitic bodies of various types and scales in Henan province is made in this paper. The average abundance is 1.17×10-9,much lower than clarke value. The gold contents of granites depend on their genetic types and increade gradully from big granitic bodies through small porphyries to alkaline granitic bodies. Furthermore, the relationship between gold contents of granitic bodies and gold mineralization and gold contents of granitic bodies of different periods and facies are also discussed.
