摘　　要：九瑞矿田是长江中下游成矿带重要的铜多金属矿集地之一。本文以成矿成晕地质-地球化学理论为指导,以九瑞地区中大比例尺地球化学调查数据为基础,剖析矿田范围内各元素地球化学异常特征以及富集、贫化规律,深度挖掘对铜矿远景评价有指导意义的相似性、剥蚀性、弱小异常及衬值组合异常等地球化学指标,为成矿预测提供有力的地球化学依据。院 Jiujiang -Ruichang copper polymetallic ore field is one of the most important nonferrous metalsconcentrations in Yangtze River iron-copper-gold metallogenic belt. In this paper, with the ore-forming and halo-forming geological-geochemical theory as a guide, basing on the medium-large scale of regional geochemicaldataanatomised the elementsgeochemical anomaly characteristics and itsenrichment and depletion regularity inJiujiang -Ruichang ore field deeply explored the geochemical indicators like similarity denudation weakabnormality and contrast combination anomaly etc. which could guide the prospecting and evaluating of coppermine and providing a powerful geochemical basis for metallogenic prognosis.
