| 中文摘要: |
| 唐家圳锰矿位于湖南省新宁县境内, 地处华南古板块加里东褶皱带邵阳断坳盆地,经勘查评价为一处风化淋滤-锰帽型锰矿床,共探获锰矿石50.3万t,矿床平均品位15.24%,为一处小型矿床。该区矿体赋存于二叠系下统当冲组上段紫红色含锰泥岩中,受复向斜核部次级向斜控制, 特别是向斜核部及转折端有利于锰矿次生富集,在成矿期断裂叠加地段,往往形成较富角砾状—块状淋滤型锰矿体。 |
| 英文摘要: |
| Tangjiazhen manganese deposit is located in xining county, hunan province, shaoyang fault depression basin, caledonian fold belt, south China ancient plate. The ore body occurs in purplish red mangane-bearing mudstone in upper part of lower Permian dangchong formation, and is controlled by secondary syncline in the core part of the composite syncline. Many manganese oxide mining sites have been found in this area. Based on the analysis and study of the characteristics of ore body and ore-controlling geological conditions of the deposit, the author summarizes the genesis of the deposit and the main ore-controlling factors in the area in order to provide reference for the exploration of the same type of deposit in the region. |
