| 摘 要： | 对邯邢地区典型夕卡岩型铁矿床白涧铁矿和西石门铁矿中不同产状的磁铁矿的成分、热电性、爆裂温度及O同位素进行了详细的成因矿物学研究。研究发现：层间矿体具有低Ti、∑REE、爆裂温度、δ18O的特征，热电性系数较小但变化范围大；接触带矿体为高Ti、∑REE、爆裂温度、δ18O的特征，热电性系数较大，变化范围小。白涧铁矿层间矿和西石门铁矿中磁铁矿的REE表现出Eu的正异常，而白涧铁矿接触带矿为负异常。白涧铁矿磁铁矿中单层矿体热电性系数具有中部小、顶底大的特征。综合磁铁矿的成因矿物学研究，以热电性的空间变化规律为基础，建立了该区夕卡岩型铁矿的成因和找矿模型。

| Abstract: | By the genetic mineralogical study of compositions,thermoelectric properties,decrepitation temperature,and O isotopes of magnetite in Baijian and Xishimen skarn iron deposit,it is found that the magnetite in the ore between carbonate layers shows low Ti,∑REE,decrepitation temperature,δ18O,and thermoelectric coefficients;that the magnetite in the ore of contacting belt shows an inverse characteristics.In the same time,REE in the ore between carbonate layers of Baijian and Xishimen iron deposit shows a positive abnormality,but that in the ore of contacting belt of Baijian shows a negative abnormality.The thermoelectric coefficient of the magnetite in the middle of a single ore body of Baijian iron deposit is smaller than that in the top or bottom.Based on the study above,especially,on the thermoelectric properties,the genetic and exploration model of skarn iron deposits in this region was built. |
