摘要
本文通过对黄铁矿的地球化学成因研究，查明吉林省放牛沟多金属矿床的围岩中存在同生沉积成因（无找矿意义）与后生热液矿化成因（具有找矿意义）地球化学异常，两者有明显区别。根据异常的元素相关性、指示元素组合、异常强度和判别分析等特征，建立了判别两种不同成因异常的标志，并利用这些标志评价了未知异常的含矿潜力。
Through the studies of geochemical genesis of pyrite ,we found out that there are syn-genetic sedimentation (having no exploratory significance)and epigenetic hydrothermal miner-alized anomaly(having exploratory significance)in the country roeks of the Fangniugou poly-metallic deposit, Jilin province,and there are obvious differences between two kinds of geo-chemicalies.The indicators discriminating two kinds of geochemical anomalies were set up ac-cording to correlation of anomaly elements,the association of anomaly element, the intensityof anomaly and the discrimination analysis etc..Meanwhile,the ore bearing of the unknownanomalies are evaluated by using the indicators.
