【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。更多还原

【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.更多还原
