摘要

利用Epsilon3 XRF型偏振能量散射X射线荧光光谱仪的Omnina全自动顺序扫描功能、经验校正和基体校正技术,建立了无损快速测定钻探岩芯样品中主要、次要和痕量元素/组分的分析方法。用强度方式计算重叠系数,康普顿线作内标扣除干扰谱线,使得样品中主要、次要和痕量元素/组分的检测更快捷,分析结果精密度和准确度更高。解谱回归分析工作曲线法可以应用于全部元素/组分。钻探岩芯样品以液压切割法制成片状,选择最佳仪器工作和分析测试条件,Omnina进行全自动顺序扫描检测各元素/组分的含量,能够满足多个样品中多个元素同时快速分析,分析检测所提供的大数据有利于钻探施工进度,可大幅提高施工生产工作效率,发挥快速分析优势。该方法在内蒙古额尔古纳矿区数月的野外试点工作中,取得了良好的地质找矿效果。

Abstract

Based on Omnina that is a Epsilon3 ED-XRF type fluorescence spectrometer with polarization scattering energy,an analysis method for determination of major,minor and trace elements in drilling rock core samples was established.It is faster to determine the major,minor and trace elements using intensity to calculate overlap coefficient and taking compton line as internal standard to subtract interference,hence the analytical results will be more precision and accuracy.In addition,the curve obtained by spectral regression analysis can be used for all of the elements/components.The core samples are cut out pieces by hydraulic cutter,more importantly,analytical instrument and operation condition should be the best.The Omnina with automatic scanning sequence can be applied to detect all of the elements/components in the samples,also it has the advantage of analyzing multiple elements rapidly and simultaneously.The established new analytical method and obtained data are extremely helpful to the drilling construction progress,which will significantly improve the efficiency of construction production. The developed method was put into use for months of field pilot work in the Erguna mining area of Inner Mongolia and we have achieved good geological prospecting results.
