黑龙江东宁金厂金矿土壤离子电导率异常特征、离子成份及找矿预测

为了解黑龙江东宁金厂金矿体土壤离子的电导率异常特征,查明金矿体中土壤离子电导率成分的离子组成以及不同种类离子的含量变化关系对电导率的贡献大小,初步探讨矿区土壤离子电导率异常的形成机理,本文对金厂金矿开展了土壤离子电导率测量,取得以下认识:(1)发现多个具有成矿远景的离子电导率异常区,经深部工程验证具有隐伏的金矿体;(2)组成土壤离子电导率异常的离子成分主要是HCO-3、SO2-4、Ca2+、Cl-、K+、Na+、F-、Mg2+、Mn2+等一套水可溶性离子,经过相关分析得出金矿电导率异常与各离子的相关系数为HCO-3>Ca2+>SO2-4>Cl->K+>Na+>F->Mg2+>Mn2+。

Conductivity Anomaly Characteristics of soil Ions and Ion Composition in the Jinchang Gold Deposit, Dongning, Heilongjiang Province and Prospecting Prediction

Abstract: 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 HCO3-, SO42-, Ca2+, Cl-, K+, Na+, F-, Mg2+ and Mn2+, and their correlation coefficients with ionic conductivity anomalies are HCO3-> Ca2+> SO42->Cl-> K+> Na+> F-> Mg2+>Mn2+.
