X射线荧光法在燕山地区金矿勘查中的研究与应用

THE STUDY OF X-RAY FLUORESCENCE METHOD AND ITS APPLICATION TO EXPLORATION OF GOLD DEPOSITS IN THE YANSHAN REGION

本文论述了Ｘ射线荧光法勘查金矿的地质、地球化学依据和物理基础，提出了解决基体效应、不平度效应和仪器一致性的方法和技术。燕山地区三个金矿区（点）的应用表明该方法可缩小找金矿的靶区，确定隐伏金矿体位置，划分金矿体的边界。

The base of geology, geochemistry and geophysics for exploring gold deposits by X-ray fluorescence method have been described. Some approaches and techniques of resolving matrix effect, unevent of effect and uniformity of instruments have been developed. Tests on three gold deposits in the Yanshan region show that the X-ray fluorescence method can narrow the aimed range of searching for gold deposits, determine the position of blind gold veins and delineate the boundary of gold bodies.
