| 中文摘要: |
| 根据杨立掌-道坨地区沉积锰的矿体厚度、品位数据资料，分析了含锰盆地展布及岩性组合特征，认为黔东杨立掌-道坨南华纪"大塘坡"式含锰盆地受古断层控制，沿65°方向展布，盆地延伸长15.0 km，宽2~2.5 km，规模巨大；含锰盆地由4个岩性带组成，从中心向外依次为：块状、气泡状菱锰矿夹碳质页岩带；碳质页岩夹块状、条带状菱锰矿带；碳质页岩夹条带状、层纹状菱锰矿带；碳质页岩、含锰碳质页岩、含锰白云岩带。根据含锰盆地岩性组合分带及其展布特征，预测含锰盆地中心中段高地一带具较好的找矿远景。 |

| On basis of thickness of sedimentary Mn ore bodies and grade is analyzed distribution and lithologic assemblages of the Datangpo style Mn-bearing basin. The basin is large in size, 15.0 km long extending in direction 65°, 2~2.5 km controlled by ancient fault. There are four lithological assemblages that outward from center is massive and bubble-like zone of rhodochrosite layer with intercalation of carbonaceous shale, carbonaceous shale zone with intercalation of massive and banded rhodochrosite layer, carbonaceous shale zone with intercalation of banded and laminae rhodochrosite layer and carbonaceous shale-Mn-bearing carbonaceous shale-Mn-bearing dolomite zone. According to the above mentioned we predict that the high land at part of the central area in the basin is potential for ore prospecting. |
