摘　　要：潼关县是我国矿产资源大县,县域南部的秦岭地区成矿条件优越,具有较好的金矿找矿前景。在详细分析和系统总结前人成果的基础上,以最新的金矿成矿理论为指导,运用GIS技术,对与金矿成矿相关的地层信息、侵入岩信息、构造信息、遥感信息、化探信息、高程信息等进行分析与提取,然后总结归纳出金矿成矿预测模型。在该模型指导下运用证据权重法对潼关地区金矿进行预测,并采用网格单元法与地质体单元法相结合的方法,最终圈定了9处成矿远景区。Tongguan is a big mineral resource county in China, the Qinling area which is located in the south of Tongguan County has superior mineralization condition and good prospecting potential of gold deposit. The authors analyzed and extracted the information such as stratum information, the intrusive rock information, the structure information, the remote sensing information, geochemical informa- tion, the elevation infornlation and so on, which was related to the gold ore mineralization in combination with the analysis and summary of the previous research results, under the guidance of the up-to-date gold ore-forming rules, using GIS technology, the authors summa- rized the prediction model of the gold deposit mineralization, which could guide the prediction of the gold deposit in Tongguan area using evidence weight method. Finally, the authors delineated nine metallogenetic prospective areas combining grid cell law with the geologic
