Abstract青藏高原沱沱河南开心岭地区,位于高原腹地北羌塘构造区,晚古生代二叠纪为滨-浅海古地理环境。该地区二叠纪铁矿床由磁铁矿体、赤铁矿体和褐铁矿体组成。富磁铁矿体上部为煤层,下部为灰岩。研究区剖面1层状富磁铁矿有两层,厚度分别为14.4 m、16.0 m,矿石TFe品位为66.30%、64.00%,具有深色和浅色矿物相间的层状特征,深色层为磁铁矿,浅色层为石英、角闪石和方解石,两层之间为5 m厚的赤铁矿层和22 m厚的蚀变辉绿玢岩,赤铁矿石TFe品位为22.20%;剖面2位于剖面1东南方向1.2 km,致密块状富磁铁矿单层厚1.52 m,磁铁矿石TFe品位为63.87%,具有方解石、白云石组成的细脉,...
