摘要
元阳县红土寨超贫磁铁矿是复合型铁矿,前寒武纪扬子地块边缘裂谷环境火山物质沉积物提供矿源。找矿方向主要为哀牢山群的阿龙组中—基性火山—沉积建造。
The ultralow grade magnetite in Hongtu Village of Yuauyang County was formed by late stage of multiple phases of metamorphism and magmatism, with ore source provided by volcanic fragments from sedimentary formation at the marginal rift of the Precambrian Yangtzi Block. The type of mineralization can be attributed into a mixed mode of early metamorphism superimposed transformation by late stage hydrothermal solution. Ore-prospecting in this area should be focused in the sedimentary formation constituted by basic volcanic rocks of the Along Formation in the Ailaoshan Group.
