摘　　要：通过对北山地区金、铜矿床植物地球化学找矿试验发现,生长在金矿区的所有植物种属中的Au和生长在铜矿区的所有植物种属中的Cu均属于极高—高衬度型,利用各植物种属中的Au和Cu含量寻找金和铜矿床具有良好的效果。根据植物地球化学异常的特征元素能区别金、铜矿种或矿化类型;矿上植物地球化学异常元素组合及分带性能定位预测掩埋或隐伏金、铜矿体的部位,同时还能推断隐伏矿体的剥蚀深度和深部矿化规模。Botanogeochemical prospecting tests conducted in gold and copper deposits of the study area show that Au in all plant species of gold ore deposits and Cu in all plant species of copper ore deposits belong to extremely high or high contrast type,and the prospecting for gold and copper deposits in the study area are effective by using Au and Cu content in a variety of plant species.On the basis of characteristic elements in plants,the gold and copper mineralization types can be identified.According to element combination and zonation of vegetation geochemical anomalies,the positions of concealed ore bodes can be predicted,and the erosion depth and deep mineralization scale of the concealed ore bodes can also be deduced.
