现场X荧光分析技术在铜矿勘探中的应用实例

In-situ X-ray Fluorescence Analysis Application Examples in Copper Exploration

采用现场X荧光测量方法对云南某铜矿远景区174件1:50000水系沉积物样品进行测量分析,发现两处明显的铜元素异常,随即进行土壤次生晕测量追踪铜异常,发现硅化蚀变带。且等值线与实验室化学分析铜含量等值线基本吻合,在测区内铜元素的浓集中心完全吻合,尤其是在铜与异常形态、异常规模和异常大小等特征吻合较好,证明现场X荧光测量方法可有效圈定和追踪异常。而数据报出时间为一天,相比于实验室化学分析方法具有显著的时效性优势。

By using in-situ X-ray fluorescence measurement method to analyse 174 stream sediment samples in a Copper prospect area of 1：50 000 Scale in Yunnan province. By which finding two distinct copper anomaly area, Then measure faint trace of soil secondary copper anomaly, discovered silicified alteration zone. And the contours and chemical analysis laboratory copper content contours basic agreement,copper in the measured area of concentration centers fully consistent, particularly good agreement in the form of copper and abnormal, unusual size and abnormal size and other features, the site X-ray fluorescence measurements proved effective delineation and tracking abnormalities. The data reported hours of the day, compared to the laboratory for chemical analysis method has significant advantages on timeliness.
