| 中文摘要: |
| 内蒙古锡林浩特地区大地构造环境复杂, 成矿地质条件优越, 有色金属矿床类型多样, 找矿潜力巨大。文章通过对内蒙古东乌珠穆沁旗珠尔嘎钼及银铅锌矿地质特征、地球化学特征及矿体特征进行分析, 总结了其成矿规律:矿体均赋存于燕山早期(黑云母)二长花岗(斑)岩(ηγ25)与泥盆系上统安格尔音乌拉组(D3a)变质粉砂质细砂岩及变质中酸性火山碎屑岩的内外接触带中,(黑云母)二长花岗(斑)岩体为成矿提供了含矿热液,北东向断裂构造为成矿提供了运移通道和容矿空间。故建议在矿区西南一带靠近主断裂及岩体的内接触带附近进一步加强银铅锌钼多金属的找矿勘查工作。 |
| 英文摘要: |
| Xilinhot area of Inner Mongolia, with complicated geotectonics, with favorable geological background for mineralization and many kinds of nonferrous metal mines is favorable for exploration. On the basis of studying the geological characteristic, geochemistry characteristic and orebody characteristic of Zhuerga molybdenum-silver-lead-zinc deposit, the following mineralization rules are summarized:the orebodies are hosted in inner and outer contact zone between early Yanshan period (biotite) monazite granite (ηγ25) and upper Devonian Angelerwula Fm. (D3a) meta-siltstone and meta-acidic to intermediate volcaniclastic rocks. The granite rock supplied the mineralizing fluid and NE trend fault supplied conduit for ore-forming fluid and mineralization space. And so the area adjoining to main fault/facture in the southwestern part of mine area and inner contact zone of granite rock bodyshould be the foucus for the future exploration. |
