【摘要】：本文以內(nèi)蒙古自治區(qū)武川縣大麻忽兔地區(qū)鐵礦調(diào)查為素材完成的。依據(jù)目前市場形勢、參照武川縣大麻忽兔地區(qū)地理位置,認為在該地區(qū)對鐵礦成礦進行研究有很大的必要性,其表現(xiàn)為:1、該地區(qū)位于良好的鐵多金屬礦成礦帶上;2、對鐵礦規(guī)�；_發(fā)適應(yīng)市場需求�；诖�,我選擇了該地區(qū)鐵礦淺析作為我的論文題目。在本次鐵礦研究過程中,首先對區(qū)域的成礦背景以及航測資料進行了系統(tǒng)的研究、分析,然后通過高精度磁法測量、地質(zhì)測量、槽探揭露以及鉆探深部驗證等綜合手段對該地區(qū)的鐵礦進行了詳盡的控制研究。通過本次調(diào)查研究,共發(fā)現(xiàn)并圈定磁性鐵礦體11條,其規(guī)模大小不等。在這一發(fā)現(xiàn)的基礎(chǔ)之上,對區(qū)內(nèi)鐵礦體進行了初步的評價并求取了鐵資源儲量。通過本次研究,對區(qū)內(nèi)鐵礦的賦存規(guī)律有了一定的認識,確定了該地區(qū)的含礦地層以及鐵礦的成礦機理;結(jié)合本地區(qū)區(qū)域成礦地質(zhì)背景,經(jīng)過將本區(qū)與周邊鐵礦床進行對比分析,確定了改地區(qū)鐵礦為沉積變質(zhì)型磁性鐵硅質(zhì)建造鐵礦;通過對鐵礦分布以及周邊環(huán)境的分析,確定了區(qū)內(nèi)鐵礦的找礦標(biāo)志為:地層標(biāo)志、巖石組合標(biāo)志、磁法異常標(biāo)志以及構(gòu)造對鐵礦的影響等幾方面。
[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.
