【摘要】：本文以内蒙古自治区武川县大麻忽兔地区铁矿调查为素材完成的。依据目前市场形势、参照武川县大麻忽兔地区地理位置,认为在该地区对铁矿成矿进行研究有很大的必要性,其表现为:1、该地区位于良好的铁多金属矿成矿带上;2、对铁矿规模化开发适应市场需求。基于此,我选择了该地区铁矿浅析作为我的论文题目。在本次铁矿研究过程中,首先对区域的成矿背景以及航测资料进行了系统的研究、分析,然后通过高精度磁法测量、地质测量、槽探揭露以及钻探深部验证等综合手段对该地区的铁矿进行了详尽的控制研究。通过本次调查研究,共发现并圈定磁性铁矿体11条,其规模大小不等。在这一发现的基础之上,对区内铁矿体进行了初步的评价并求取了铁资源储量。通过本次研究,对区内铁矿的赋存规律有了一定的认识,确定了该地区的含矿地层以及铁矿的成矿机理;结合本地区区域成矿地质背景,经过将本区与周边铁矿床进行对比分析,确定了改地区铁矿为沉积变质型磁性铁硅质建造铁矿;通过对铁矿分布以及周边环境的分析,确定了区内铁矿的找矿标志为:地层标志、岩石组合标志、磁法异常标志以及构造对铁矿的影响等几方面。
[Abstract]:Based on the investigation of iron ore in hemp huhuyu area in Wuchuan County, Inner Mongolia Autonomous region, according to the current market situation, and referring to the geographical location of hemp huhuyu area in Wuchuan County, it is considered that it is necessary to study iron ore mineralization in this area. This area is located in the good iron-polymetallic ore metallogenic belt No. 2, and adapts to the market demand for the large-scale development of iron ore. Based on this, I chose the iron ore analysis in this area as my thesis topic. First of all, the metallogenic background and aerial survey data of the region are systematically studied and analyzed, and then through high-precision magnetic survey, geological survey, The ore deposits in this area have been thoroughly controlled by means of trough exploration and deep drilling verification. Through this investigation and study, 11 magnetic iron ore bodies have been discovered and delineated, with varying sizes. On the basis of this discovery, A preliminary evaluation of the iron ore bodies in the area is carried out and the reserves of iron resources are obtained. Through this study, the regularity of the occurrence of iron ore in the area is recognized, and the ore-bearing strata and the ore-forming mechanism of the iron ores in this area are determined. According to the regional metallogenic geological background of this area, by comparing and analyzing the ore deposits in this area and the surrounding iron deposits, it is determined that the iron ore deposits in the modified area are sedimentary metamorphic ferrosiliceous iron deposits, and through the analysis of the distribution of iron ore and the surrounding environment, The ore-prospecting criteria of iron ore in this area are as follows: stratigraphic marker, rock assemblage marker, magnetic anomaly marker and the influence of structure on iron ore, etc.
