摘要
羊露河上游铁矿位于北祁连西段加里东褶皱带西段。铁矿体赋存于下元古界长城系上岩组含铁角闪片岩中,含矿层位严格受地层层位控制,矿石构造具有同生沉积特征,并显示了热液富集作用特点,具“似鞍山式”铁矿成因特征,矿石品位较高,盲矿体存在的可能性较大,因此具有重要的找矿意义。
Iron ore deposits in upper reach of Yangluhe river are situated in the west Calidonian fold belt of the west Qilianshan mountain. Ore bodies occur in Fe-bearing amphibolite of the Upper formation of Lower Proterozoic Changcheng system. The ore is strictly stratobound and characterized by syn-sedimentation and hydrothermal enrichment thus pocesses the feature of Anxhan style iron ore. Ore grade is relatively high and blind ore body may occur. The deposit is potential for further exploration.
