X射线粉晶衍射仪在山东蒙阴金伯利岩蚀变矿物鉴定中的应用

Identification of Alteration Mineral Composition of Kimberlite from Shandong Mengy by X-ray Powder Diffractometer

  • 摘要: 山东蒙阴金伯利岩组成矿物以蚀变矿物为主,X射线粉晶衍射仪鉴定结果显示无矿金伯利岩矿物组分为方解石、白云石、石英、钙锆钛矿,标志性矿物为白云石和钙锆钛矿;贫矿金伯利岩矿物组分为蛇纹石、方解石、钙铝榴石、磁铁矿和金云母,标志性矿物为钙铝榴石;富矿金伯利岩矿物组分为蛇纹石、方解石、绿泥石、磷灰石、磁铁矿和金云母,标志性矿物为绿泥石和磷灰石。采用X射线粉晶衍射仪鉴定金伯利岩蚀变矿物组合,寻找蚀变矿物组分变化与金伯利岩含矿性的关系,利用标志性的蚀变矿物判断金伯利岩无矿、贫矿还是富矿,是非常有意义的。

     

    Abstract: The kimberlite from Shandong Mengy mainly consists of alteration minerals. X-ray powder diffraction results showed that the barren-kimberlite consists of calcite, dolomite, quartz, calzirtite with dolomite and calzirtite as the signature minerals, the lean-kimberlite consists of serpentine, calcite, grossular, magnetite and phlogopite with grossular as the signature mineral, the rich-kimberlite consists of serpentine, calcite, chlorite, apatite, magnetite and phlogopite with chlorite and apatite as the signature minerals. The research results indicate that X-ray powder diffraction is a powerful tool for identifying kimberlite alteration mineral composition, studying on the relationship between component change of alteration minerals and ore potentiality of kimberlite, and assessing barren-kimberlite, lean-kimberlite and bonanza-kimberlite based on the signature minerals.
