【摘要】 用中子活化分析技术及新研制的地气采集装置,在山东省东季金矿上进行了地气探测及异常研究。文中讨论了对于找隐伏金矿,INAA优于PIXE技术。在构造含矿带上方有明显的La、K、Na、Fe、Sc、Au、As、Cr、Sb及Zn等元素的地气异常。在隐伏矿上方有Au、As、Cr、Sb及Zn等元素异常存在。认为地气中这些金属元素的异常是一种良好的地下金矿化的地表直接指示。更多还原

【Abstract】 Abstract:Using the instrumental neutron activation analysis and the newly-designed geogas collection device, we performed geogas survey and anomaly investigation over the Dongji gold deposit in Shandong Province.It seems that INAA is superior to PIXE so far as the prospecting for con-cealed gold deposits is concerned.There are obvious geogas anomalies of such elements as La,k, Na, Fe,Sc, Au, As, Cr, Sb and Zn over the structural ore-bearing belt;anomalies of Au, As, Cr,Sb,Zn and some other elements exist over concealed ore deposits. Anomalies of these metallic elements serve as a good direct indicator for subsurface gold mineralization.更多还原
