摘要
蒙库铁矿位于阿尔泰多金属成矿带的中段,蒙库复背斜北东翼部次级向斜铁木下尔滚向斜核部及其两翼,含矿地层为下泥盆统康布铁堡组下亚组,岩性为一套中深变质的火山岩。矿体与围岩接触界限清楚,与地层同步褶曲呈向斜形态。文章以区域成矿条件,矿床地质特征为基础,根据对矿石微量元素组分分析、硫同位素特征研究认为,矿床成因应属海相火山喷发-沉积受变质改造矿床。
Mengku Iron deposit is situated in the middle of the Altai polymetallic mineralization belt, in the core and on the both limbs of the sub-scale Tiemuxiaergui sycline and at the northeast limb of Mengku anti clinorium. The ore is hosted by the lower subgroup of Lower Devonian Kangbutiebao group which is composed of medium-high metamorphic volcanics. Ore bodies are conformably and synchronously folded with the host. Studies on regional ore-forming condition, characteristics of the ore deposit, micro-element of ore and S isotopes show that the deposit is a metamorphosed marine volcanic eruption-sedimentary Fe deposit.
