摘要
赤铁矿赋存于忙怀组/大新山组之间不整合—断层破碎带中,脉状矿体,鳞片状集合体和皮壳状结构,火山喷发穿插—沉积变质型。属活动边缘裂隙喷发一沉积产物。
The hematite deposit is in the unconformity-fauh fractured zone between Manghuai Formation and Daxinshan Formation. The ore body is veined, in flaky aggregate and crustification. It belongs to the volcanic eruption intercalating sedimentation metamorphism type, which is formed by the active margin fissure eruption-sedimentation.
