| 摘 要： | 东大山磁铁矿地处阿拉善隆起Cu-Ni-Pt-Fe-REE-P-石墨-芒硝-盐类成矿带西缘,属于产在前长城系龙首山群一套变质岩中的沉积变质型磁铁矿床,分析其航磁异常特征及找矿标志对同类型矿床勘查具有借鉴意义。通过收集矿区地质资料,基于在矿区及周边开展的1∶5万航磁测量及异常查证情况,分析了矿区地质、地球物理和遥感影像特征,提出了沉积变质型铁矿的找矿标志,并圈定了找矿远景区1处。

| Abstract: | The Dongdashan magnetite ore deposit in Yongchang County is located in the western margin of Cu-Fe-Ni-Pt-REE-P-graphite, glauber''s salt ore belt in the Alashan uplift. It is a sedimentary-metamorphic magnetite ore deposit occurring in a set of metamorphic rocks of the pre-Changcheng System Longshoushan Group. Geological, geophysical and remote ensing characteristics and prospecting marks of the deposit are analyzed. The analysis can be referred to prospecting of the similar deposits in the area. And 1 target has been located according to the analysis. |
