摘　　要：杜家崖金矿为层间滑脱蚀变岩型金矿,不同于山东蚀变岩型、石英脉型及破碎角砾岩型金矿。前人对该矿床的研究极少,因此,希望通过对该矿床矿石中黄铁矿热电性的研究,可以为深部找矿提供依据。利用BHTE-06热电系数测试仪对Ⅰ号矿体37件矿石样品中1692粒黄铁矿进行了热电系数分析,并用BHMR-08型半导体矿粒调温电阻测试分析仪测出了38件矿石样品中1900粒黄铁矿的热电阻率。根据所得热电性系数数据计算出该矿床的黄铁矿形成温度范围为78.6～380.8℃,主要集中在141.3～350.9℃。据所得数据进行黄铁矿热电系数及热电阻率填图,可推测36～38、54勘探线海拔-100m以下附近的区域可能为富矿段,成矿远景较好。Different from other types（quartz vein,alteration and broken breccia） of gold deposits in the Shandong Province,the Dujiaya gold deposit,which has been studied very little,is an interlayer gliding alteration type deposit.It hopes that the study of the thermoelectricity of pyrite can provide evidence for deep exploration.1692 pyrite grains from 37 ore samples of theⅠorebody were analyzed by BHTE-06 type thermoelectric instrument and 1900 pyrite grains from 38 ore samples of theⅠorebody were analyzed by BHMR-08 type impedance analyzer.The calculation on the basis of the measured thermoelectric coefficients indicated that the pyrite crystallization temperatures are in the range of 74.3-387.5℃ and mostly in the range of 141.3-343.4℃.Based on the map of thermoelectric coefficient and thermal resistance rate,this study predicts that locations of-100 meter below the 36～38 and 54 prospecting lines may contain high grade gold ore and have good perspective of mineralization.
