凤凰庄测区位于灵北断裂带灵山沟金矿区南西侧。本次选择了蚀变填图和地表构造地球化学测量作为多元异常信息找矿的主要手段，测量范围约3 km2，绢英岩化蚀变异常区可作为矿化元素聚集区标志，钾化蚀变异常可作为矿化元素活化区标志。测区内发现3处高浓度并成规模的Au元素异常带，Au元素含量分形特征显示Au经历过多次成矿富集作用，结合多元统计分析，厘定测区构造地球化学找矿标志为Au-As-Sb元素组合与斜交因子Y（i，2）和Y（i，3）得分异常。根据蚀变填图和构造地球化学测量综合信息，圈定了3处找矿靶区。
Fenghuangzhuang survey area is located in the southwest of Lingshangou gold district in Lingbei fault zone.Structural alteration mapping and surface tectonic geochemistry were chosen as the means for ore prospecting in the study.The survey area is about 3 km2 .Sericite-quartz alteration anomaly is recognized as the marker of mineralized elements enrichment zone,while potassic alteration anomaly as mineralized elements activation zone.Three scaled high concentration Au anomalies were found in the survey area.Fractal dimension statistics of Au showed the area experi-enced multiple gold mineralization.Combined with multivariate statistical analysis,the study determined Au-As-Sb association anomalies and oblique factor score anomalies of Y (i,2) and Y (i,3) as clues of tectonic geochemistry prospecting.Three prospecting targets were delineated based on structural alteration mapping and tectonic geochemis-try.
