中文摘要:
      云南澜沧县芒洪铁矿是近期开展1∶5万区域地质矿产调查新发现的铁矿床。芒洪铁矿为海相火山-沉积变质型矿床,矿体呈层状、似层状赋存于惠民增生杂岩中,铁矿体的分布受地层层位、岩性建造、火山-沉积旋回等因素联合控制;矿区的物化遥异常与已发现铁矿吻合较好,成矿条件有利,找矿标志明显,具有较好的找矿前景。
英文摘要:
      The Manghong iron deposit is a newly discovered typical marine volcanic sedimentary metamorphic deposit during geological and mineral resources survey at scale 1:50000 carried out in resent years. The ore bodies are stratified and stratoid, occurred in the blocks of the Huimin accretionary complex (O1-2Hmc). The formation and distribution of these iron ore bodies are controlled by combination of stratigraphic horizon, lithologic formation, volcanic sedimentary cycle and some other factors. Anomalies of geophysics, geochemistry and remote sensing imageology are all consistent with these discovered iron ore bodies indicating that the Huimin accretionary complex with obvious prospecting marks is favorable in metallogenic conditions and potential for further prospecting.
