Conductivity Anomaly Characteristics of Soil Ions and Ion Composition in the Jinchang Gold Deposit, Dongning, Heilongjiang Province and Prospecting Prediction
摘要
The purpose of this paper is to describe the ionic conductivity characteristics of soil in the Jinchang gold deposit of Dongning, Heilongjiang Province, and to study their soil ion composition, ion content changes with different ion types, their contribution to ionic conductivity, and the formation mechanism of soil ion conductivity anomalies. Through measurements of the soil ion conductivity, it is suggested that: (1) there are a number of soil ion anomaly areas with prospecting potential, where buried gold ores were found through deep engineering validation. (2) The components of soil ion with ionic conductivity anomalies include soluble ions of HCO-3, SO2-4, Ca2+, Cl-, K+, Na+, F-, Mg2+ and Mn2+, and their correlation coefficients with ionic conductivity anomalies are HCO-3> Ca2+> SO2-4>Cl-> K+> Na+> F-> Mg2+>Mn2+.
