摘　　要：应用多元素X荧光测量仪对川西北某金矿外围约4.05km2勘查区进行扫面工作,通过对As,Pb,Cu,Zn,Fe等指示元素的测量来寻找和圈定金矿化带,并以γ能谱测量与土壤快速α测量为辅助手段,最终综合化学金分析来捕获并确认金矿的有利赋存位置,为山地工程布设提供依据,提高了在该金矿外围找矿的成功率。The multi-element of x fluorescence spectrometry is applied for scanning work at about 4.05km2 external prospecting area of a goldmine in northwest of Sichuan province.Through the measurement of the indicator elements of As,Pb,Cu,Zn,Fe,the gold mineralization belt is prospected and delineated.With the aid of γ-ray spectrometry and rapid soil measurement of α,the favorable gold occurrence location is captured after the final comprehensive chemical analysis of gold.This provides a basis for the engineering planning,and improves the rate of success on ore prospecting in external gold mine.
