| 摘 要： | 球路奥窝头铁矿床为小型规模铁矿床，有用矿物以磁铁矿为主，有害杂质含量较低，但矿石较细，属中等选矿石。研究了该地区的矿床地质特征及成矿成因。研究得出，通过1∶〖KG-*2〗1万高精度磁法测量，圈定磁异常3处，初步圈定了成矿有利靶区；查明了矿区地层、构造、岩浆岩的分布、规模、产状及与矿化的关系以及矿体分布、形态、规模、产状及矿石质量；矿床受火山喷流沉积旋回、岩浆岩、围岩岩性等的综合控制。矿区地理条件优越，开发条件有利，矿区开发经济效益和社会效应均较好。研究为矿业开发提供了资源依据

| Abstract: | Qiulu Aowotou Iron Ore Deposit is a small-scale iron ore deposit.The useful minerals are mainly magnetite，with low content of harmful impurities，but the ore is fine，belonging to medium concentration ore.The geological characteristics and metallogenesis of the deposit in this area are studied.The study shows that 3 magnetic anomalies have been delineated through 1 ∶〖KG-*2〗10 000 high-precision magnetic survey，and the favorable target areas for mineralization have been preliminarily delineated.The distribution，scale and occurrence of strata，structures and magmatic rocks in the mining area and their relationship with mineralization，as well as the distribution，shape，scale，occurrence and ore quality of the ore body have been ascertained.The deposit is comprehensively controlled by volcanic exhalative sedimentary cycle，magmatic rock and wall rock lithology.The mining area has superior geographical conditions，favorable development conditions，and good economic and social benefits.The study provides a resource basis for mining development. |
