发布时间：2018-07-24 14:21
【摘要】：凯勒克赛依铁矿床是新疆阿尔泰唯一的小型镜铁矿床,赋存于一套变质火山-沉积岩系中,近矿围岩为白云母石英片岩,矿体呈层状,与地层产状一致,矿石具有块状、条带状、条纹状构造,矿石中金属矿物主要为镜铁矿(TFe O=87.349%~88.988%,Ti O2=0~1.042%,Al2O3=0.036%~0.256%),矿化具有沉积特征。近矿围岩镜铁矿白云母石英片岩锆石LA-MC-ICP-MS U-Pb谐和年龄为(375.6±0.6)Ma,限定成矿时代在376 Ma左右,即中泥盆世成矿,是阿尔泰为数不多的中泥盆世成矿作用的产物。同时也厘定含矿的变质火山-沉积岩系属中—晚泥盆世阿勒泰镇组,不是前人认为的早泥盆世康布铁堡组。
[Abstract]:The Kellerkesay iron deposit is the only small mirror iron deposit in Altai, Xinjiang, which occurs in a set of metamorphic volcano-sedimentary rock series. The surrounding rock near the ore is Muscovite quartz schist, the ore body is layered, consistent with the stratigraphic occurrence, and the ore is massive. Striped and striped structure, the main metallic minerals in the ore are goernetite (TFe 87.349). The mineralization is characterized by sedimentary characteristics, such as: (TFe) (TFe) (87.349) and (88.988) TiO2 + (1.042) and (0.036%) Al _ 2O _ 3 (0. 036 ~ 0. 256%). The zircon LA-MC-ICP-MS U-Pb harmonic age of Muscovite quartz schist is (375.6 卤0. 6) Ma. and its metallogenic age is about 376Ma, that is, middle Devonian mineralization, which is the product of a few middle Devonian metallogeny in Altai. It is also determined that the metamorphic volcano-sedimentary series of ore-bearing rocks belong to the Altaizhen formation of the Middle-Late Devonian and are not the early Devonian Shikangbutebo formation.
