摘　　要：核技术用于金矿勘查的方法主要有Ｘ射线荧光法、γ能谱法、氡（射气）法、中子活化分析法等。本文论述了核技术勘查金矿的地质、地球化学依据、物理基础和方法技术。实践表明：以γ能谱方法（Ｋ，Ｋ／Ｔｈ为参数）可圈定与金矿化有关的钾化蚀变带；以Ｘ射线荧光法可确定含金矿脉的位置，原位划分金矿体边界；中子活化分析法（ＲＥＥ）可揭示深部盲矿体。Nuclear techniques used for gold exploration mainly include X-ray fluorescence analysis,gamma-ray spectrometry, radon emanation method and neutron activation analysis,etc.This paper discusses the geological and geochemical basis,physical foundation and methods(techniques) while nuclear techniques are used to explore gold deposit. Many-years' practicein the study area has indicated that the potassic alteration zone associated with gold mineralization can be delineated by using gamma-ray spectrometric method (K, K/Th asparameters ) lthe location of gold-bearing veins and the boundary of gold orebodies can be determined on the spot by using X-ray fluorescence analysis land blind orebodies at depth canbe revealed by using neutron activation analysis (REE)method.
