| 中文摘要: |
| 区内氧化锰矿皆赋存于含锰层系中,呈似层状或透镜状产出,且与围岩略具同步褶曲,表明锰矿系-古风化型锰矿经后期的进一步氧化、富集所形成的.这一认识对指导区域找矿取得了较好的效果. |
| 英文摘要: |
| This is a typical weathered stratabound manganese ore deposit, The Qixia Formation of the lower Permian Series is a Mn-bearing horizon which was exposed to surface during Indo-China Movement, It is formed by weathering-leaching concentration till Quarternary More than 40 ore bodies are exclusively located in the Mn-bearing bed occuring as layered lenses synchronousty folded with the enclosing rock.The Mn-bearing bed is not only the source bed but also the enclosing rock. It is concluded that ore formation in this area needs two prerequisites, ie. the source bed to provide the ore materials and the protracted weathering condition to leach and concentrate the ore materials among which any one can not be absent. With this guide the authors have made successes in the recent year's exploration for manganese ore in this area. |
