摘　　要：迎丰地区位于陕西石泉—旬阳国家级金矿整装勘查区内,成矿地质条件和找矿前景良好。通过开展1∶2.5万土壤地球化学测量,对10种元素进行变异系数、相关性分析、聚类分析,结果显示:Au异常分布不均匀,离散程度较大,为主要成矿元素。通过对Au异常和综合异常的研究,结合成矿地质条件和矿化特征,圈出金蚀变带5条。通过地化剖面、槽探、钻探工程验证,共圈出17条金矿(化)体,进一步证实该地区找矿前景良好。Yingfeng Area is located within Shiquan-Xunyang National-level Gold Deposit Exploration Area in Shaanxi Province,characterized by favorable metallogenic geological conditions and promising prospecting potential.A 1∶25000 soil geochemical survey was conducted,analyzing the variation coefficients,correlations,and cluster analysis of 10 elements.The results indicate that the distribution of Au is uneven,with a high degree of dispersion,identifying it as the primary ore-forming element.By studying Au anomalies and comprehensive anomalies in conjunction with metallogenic geological conditions and mineralization characteristics,5 gold alteration zones were delineated.Verification through geochemical profiles,trench exploration,and drilling projects resulted in the delineation of 17 gold ore(mineralized)bodies,further confirming the area s promising prospecting potential.
