阿克陶孜洛依铁矿床特征及矿床模型
摘要
孜洛依铁矿位于西昆仑山区，出露于康西瓦断裂与塔阿西断裂之间，赋存于古元古界布伦阔勒群黑云母石英片岩。本文从区域地质背景入手，收集区域地质、构造演化、岩石、矿床勘查等资料，结合野外地质剖面和样品测试结果的分析，归纳、总结矿床地质特征，通过对成矿地质背景、成矿条件、地球物理、地球化学特征的综合研究，认为该磁铁矿为火山沉积变质型。通过矿床地质、地球化学等综合研究，认为孜洛依铁矿经历了三期成矿作用：早期岩浆活动形成了火山-碎屑岩沉积建造，后期经区域变质作用而形成磁铁矿，后期的岩浆侵入活动对已形成的磁铁矿体进行改造。通过控矿因素，建立了该区域找矿模型：古元古界沉积变质地层中深变质岩系，带状磁异常中明显的局部异常，化探Fe、Mn、V、Ti、Co等的化探单元素或组合异常明显，并且无明显的Cr、Ni局部异常。对该区域进行了靶区预测，确立了3个：深部靶位，孜洛依北一带和苏巴什靶区。
Ziluoyi iron ore is in the mountain area of West Kunlun, which is exposedbetween the Kangxiwar fault and Tarxi fault. This essay starts from the geologybackground of the region, gather infromation of areal geology, tectonic evolution,rocks, ore deposit prospecting and so on, which combines with analysis test results offield geology sections and samples, sum up and summarize geogory features ofdeposit. Acquired through comprehensive research the features of the geogorybackground of iron ore, minerogenetic condition, physical geography, geochemistry,the essay considers the auriferous strata in this iron ore area is made up with a set ofancient Blunculer Group and silicoferrites metamorphism. The main lithology isbiotite gneissic rocks and biotite quartz schists. This stratum is similar to magnetitedeposits in rock association, metamorphism deformation stage, ore-bearing potentialand other parts, such as Zankan, Laojing and so on. Studies about comprehensivestudy of geology of ore deposit, geochemistry lead to put forward that Ziluoyi iron orego through four metallogenesis. In the early period, it forms lava full of iron bymagmation. In the later period, it forms biotite quartz schist with enriched iron rock inthe course of regional dynamic heat flow metamorphism. Then it forms gershgorimband full of iron and silicon, thus forms metamorphosed sedimentary type. Afterbeing ore, the invading magmatite has an effect on late reformation to enrich. At last,with ore-controlling factors it builds regional ore-prospecting model by hypergeneoxygenizement and denudation deterioration: In the aleoproterozoic, in the stratum ofsedimentary metamorphism series of hypometamorphic rocks have obvious localanomaly in linear magnetic anomaly, chemical prospecting Fe、Mn、V、Ti、Co andother singletons or assembles which are obvious anomaly, and without obvious localanomaly of Cr、Ni. This area has been predicted in target areas to establish3, whichare deep target position, the northern stair Ziluoyi target position and prospect of Subas iron ore.
