摘　　要：红旗岭矿区3号岩体由辉长岩相、辉岩相组成,矿体产于辉岩相中。岩体镁铁比值(m/f)为1.27～4.93,平均值为3.54,属铁质超基性岩。岩体稀土配分模式呈右倾的轻稀土富集型。矿石硫同位素组成(δ34S)为-1.7‰～+0.3‰,平均值为-0.68‰,与陨石硫同位素组成一致。其岩体岩相组成、赋矿岩石和矿物成分、岩石化学、主成矿元素、稀土元素、硫同位素组成特征,与矿区内1号、7号、2号、9号等含矿岩体具有比较明显的一致性,反映了矿区内含矿岩体形成于同一期构造岩浆活动,岩浆及成矿物质来源具有同源性。The rocks of the 3rd ore-bearing rocks in Hongqiling area are composed of gabbro and pyroxenite and Ore-bearing come from pyroxenite facies. The ratio of Mg/Fe（m/f） is 1.27 - 4.93 ,with a 3.54 average,which indicates that that are iron uhramafic rocks. The REE patterns of the rocks show a relatively right deviation and enriched in LREE. Sulphur isotope of the ore was - 1.7‰～ ＋ 0.3‰,with a -0.68‰ average, which is identical with the sulphur isotope of meteorolite. The 3rd ore-bearing rocks have apparent consistent and similarity with the other ore-bearing rocks （ the 1 st, the 2nd, the 7 tb, and the 9th） in petrofacies, ore-bearing rocks and its mineral components,petrochemis try features,main ore elements, REE features and its patterns,sulfur isotope component. All the ore-bearing rocks in the ore field formed in the same tectono-magmatic activities. Magma and mineralization have the same sources, and formed the same ore deposits.
