| 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.

| Abstract: | 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. |
