| 摘 要： | 便携式X射线荧光光谱(PXRF)是针对野外原位快速分析而发展起来的一项新技术,常被用于岩石露头地球化学研究和土壤重金属污染评价等方面.本研究以安徽省泥河铁矿钻孔为例,在野外对5个钻孔的岩心系统划分岩性段,利用便携式X射线荧光光谱仪原位测量每个岩性段的Fe、Mn、Cr、Co、Ni、Ti、V、Cu、Zn、Pb、Ag、Mo、K、Ca、As、Sb、Bi、Cs、Zr、Nb等元素含量,绘制钻孔各元素含量分布图.研究发现,(1)利用PXRF技术获得的岩心Fe元素高含量部位与根据化学分析得到的铁矿石品位数据而圈定的磁铁矿体范围吻合较好;(2)Fe元素和Fe-V-Mn-Cr-Ni-Ti-Bi组合异常、Zn元素和Zn-Cu-Cd组合异常分别对铁矿化和铜、锌矿化具有较好的指示作用;(3)K、Ca异常分别对钾长石化、硬石膏化等蚀变具有较好的指示作用.由此可见,PXRF技术在野外岩心矿化和蚀变信息识别中具有方便、快捷、实用、可靠、无损、成本低廉等优点.
