摘　　要：磁铁矿体赋存于元古界澜沧群南勒组(Ptnl)和华力西期花岗岩体(γ34)接触带内,圈定7个矿体,严格交接触带控制,经后期低温热液作用叠加富集。The magnetite ore body is in the contact between Proterozoic Lancang Group Nanle Formation（Ptnl）and Variscan granite body（γ34）.There are 7 ore bodies outlined.They are controlled strictly by the contact,and superimposed by the later low T hydrothermal concentration.

关 键 词：变质交代磁铁矿 斑块状细粒状 南勒组 花岗岩 接触变质带 云南景洪先坦
