摘要
通过对牟定安益地区42号航磁异常开展1∶1万路线地质调查、1∶1万地磁剖面测量、1∶1万土壤地球化学剖面测量与1∶1万重力剖面测量工作,基本查清了异常源由磁铁矿化基性-超基性岩体引起,判断本异常区有寻找"安益式"基性-超基性含铂钯磁铁矿的意义,为今后在该异常区寻找铁矿提供了找矿方向。
On the basis of comprehensive analysis of the geological survey,ground magnetic section,geochemical soil section and gravity profile at a scale 1∶10 000 in the 42 aeromagnetic anomaly of Anyi area,the source of aeromagnetic anomaly have been found,it is caused by magnetite basic-ultrabasic rock.We make an analysis of its significance in prospecting for ' Anyi' type basic-ultrabasic Pt-Pd magnetite and suggest the direction for searching for iron ores in this region.
