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。
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.
