摘要
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.
