摘　　要：陕西省金矿资源丰富,矿床类型多样,其属陕西的优势矿产之一。金矿产地主要分布于西安、宝鸡、渭南、汉中、安康和商洛等市所辖之陕南秦巴山区。以近年来完成的《陕西省潜在矿产资源评价报告》为基础,笔者系统收集和整理了陕西已有金矿地质资料,总结了金矿的成矿地质条件及时空分布规律;采用综合信息矿产预测理论和方法,对金矿资源潜力进行了预测。划分预测工作区11个,圈定金矿找矿远景区56个、重点找矿靶区45个,预测2000 m以浅潜在金矿产资源4477918 kg,可利用潜在矿产资源2248102 kg。其研究成果和认识可作为新一轮找矿突破战略行动金矿勘查工作部署的参考资料。Shaanxi Province is rich in gold resources and has various deposit types.It is one of the dominant minerals in Shaanxi Province.Gold deposits are mainly distributed in the Qinling–Bashan Mountains of southern Shaanxi Province under the jurisdiction of Xi’an,Baoji,Weinan,Hanzhong,Ankang and Shangluo.Based on the Evaluation Report of Potential Mineral Resources in Shaanxi Province completed in recent years,this paper systematically collected and sorted out the geological data of existing gold deposits in Shaanxi Province,and summarized the metallogenic geological conditions and spatio–temporal distribution of gold deposits.Based on the theory and method of comprehensive information mineral prediction,the potential of gold resources is forecasted.11 prediction work areas were divided,56 gold prospecting potential areas and 45 key prospecting targets were delineated.The shallow potential gold mineral resources of 2000 meters were estimated to be 4477918 kg and available potential mineral resources of 2248102 kg.The research results and understanding can be used as reference for the deployment of gold exploration in the new round of strategic action of prospecting breakthrough.
