摘要
黄铁矿的热电性主要由呈类质同象替代的杂质元素引起。富硫且含As较高的黄铁矿,热电性显示空穴导型,热电系数为正值;亏硫而富Co,Ni,Se,Te的黄铁矿,则显示电子导型,热电系数为负值。黄铁矿的矿化系数大于60％是高凡银金矿床的找矿标志之一。高凡银金矿床中黄铁矿热电性具有空间分带特征,矿体上部为空穴型,中部为混合型,下部为电子型,用此可判断矿体剥蚀深度和预测深部矿体。
The thermoelectricity of pyrite is mainly caused by impurity elementssubstitution as isomorphism. Pyrite rich in S and As shows hole conductivityand positive thermoelectricity coefficient. Pyrite lacking in S and rich inCo, Ni, Se and Te shows electron conductivity and negative thermoelectricitycoefficient. Pyrites of different geneses contain different kinds and contentsof impurity elements, So they are different in thermoelectricity which canbe a typomorphic characteristics of distinguishing different mineralizations.The mineralization coefficient which is more than 60% can be an indicatorfor gold deposits. The thermoelectricity of pyrites in the Gaofan Ag-Audeposit has zonality: the upper orebody shows hole conductivity, the middleshows mixed conductivity and the lower shows electron conductivity, whichcan be used to assess the denudation depth of orebodies and prognosticatethe dccp orebodies.
