| 中文摘要: |
| 在内蒙中部东升庙矿区元古宙狼山群第二岩组第四岩性段中,发现颇具规模的菱铁矿层.虽然菱铁矿体与含铜硫铁多金属矿体同出现于一个岩性段中,但大部分菱铁矿是独立矿体. |
| 英文摘要: |
| Siderite deposit in certain scale is found in the second member of Langshan group (Proterozoic) within the Dongshengmiao copper-bearing pyritepolymetal mining district which is tectonically situated at the south metallogenic belt of west part of Proterozoic aulacogen in the middle of Inner Mongolia By thermal differential and X-diffraction analysis, siderite amounts for 63.2-86.3% of the carbonate iron ore. And 84-98% siderite is converted to magnetite at temperature>550℃ in inclusion explosion test. Consequently, siderite ore can be a kind of good quality iron ore by firing. This paper verifies that siderite ores are individual bodies though they occur in the same horizon with copper-bearing pyrite-polymetal ore bodies. |
