钻孔岩芯多元素原位X荧光分析技术及应用

Research on Multi-element In-situ XRF Technique on Drilling Cores and its Application

与化学分析相比,X荧光分析具有更加快捷、成本低廉的优点。只要技术方法得当,X荧光分析能在一定程度上替代化学分析,从而快速获取钻孔岩芯的元素组成及含量。对黄沙坪ZK1601,ZK12101的取样岩芯进行测量,得到Cu,As,Ca,Cr,Fe,Mn,Ni,Sr,Ti,W,Pb,Zn多种元素的含量随深度的变化情况,结合物探、化探,成功圈定了铜矿和其他元素富集地段,证明了X荧光分析技术在钻孔岩芯测量中的有效性。

Comparing with the chemical analysis,X-ray fluorescence analysis has feature of more efficiency and lower cost.With proper technique,X-ray fluorescence analysis can substitute the chemical analysis in a certain extent to rapidly get the ultimate composition and the content of the drilling cores.The borehole cores of ZK1601 and ZK12101 at Huang Shaping are measured,and the variation relationship between the contents of Cu,As,Ca,Cr,Fe,Mn,Ni,Pb,Sr,Ti,W,Pb,Zn,with the depth are given.And combining with geophysical and geochemical exploration,the enrichment depth of copper mine and the other elements are successfully delimited.That X-ray fluorescence analysis is effective in measurement of drilling cores.
