本文阐述了X射线荧光法测金的物理基础和地质、地球化学依据。实验表明:在火山岩多金属矿床上,用轻便型X射线荧光仪测量与金相关的钡的特征,X射线强度能够估算粉样中的金含量,由此得出的金含量与化学分析金含量之间的误差,均达到部颁分析误差标准;在原生露头上,用该方法能够准确地圈定富金地段。 This article describes the physical basis of X-ray fluorescence gold determination and geological, geochemical basis. Experiments show that the characteristics of barium, which are related to gold, can be measured by portable X-ray fluorescence spectrometry on volcanic polymetallic deposits. The X-ray intensity can estimate the gold content in the powder sample. The gold content and chemical analysis gold content Between the error, have reached the ministerial analysis of error criteria; in the native outcrop, using this method can accurately delineate the rich area.
