库姆塔格菱铁矿床,位于天山东部库姆塔格沙垄中段东侧。1976年,我们参加东疆富铁矿会战工作,有机会对该矿床地质背景、矿体和矿石矿物共生组合关系、围岩蚀变特征等进行研究,获得一些粗浅认识,初步予以总结,以供参考。一、矿床产出地质背景库姆塔格地区,属阴山——天山东西向复杂构造系中北天山构造带中东段的南缘,亦即北天山华力西地槽褶皱带觉罗塔格复背斜的西南侧。出露的地层、构造形迹特征及岩浆岩表明,在地质历史上这里是非常活动的地带;特别是晚古生代期间,堆积了巨
Qomtagge siderite iron ore deposit, located east of Tumshan sand dune east of middle section. In 1976, when we participated in the battle of iron ore in Dongjiang, we had the opportunity to study the geological background of the deposit, the symbiotic relationship between ore bodies and ore minerals, the alteration characteristics of the surrounding rock, and get some superficial understanding and preliminary summary for reference. First, the geological output of the deposit Kumtag area, is Yinshan - Tianshan east-west complex structure in the middle of the northern Tianshan tectonic belt in the southern margin of the middle, that is, the North Tianshan Variscan trench fold belt Jueluotage The southwest side of complex anticlines. Exposed strata, tectonic features and magmatic rocks indicate that this area is very active in the geological history; in particular, during the Late Paleozoic, giant
