摘要
贵州铜仁松桃锰矿区位于扬子陆块与华南陆块的过渡区,跨越上扬子地块和江南造山带。通过对本区7个较大成锰沉积盆地中大塘坡组地层进行对比分析,总结出本区大塘坡组地层厚度与锰矿品位及矿体厚度呈正相关性,即大塘坡组地层厚度越厚,锰矿品位越高、矿体厚度越厚,其中,锰矿品位与大塘坡组第二、三段地层厚度呈较强正相关性,锰矿体厚度与大塘坡组第一段呈较强正相关性。同时大塘坡组及锰矿体的厚度变化表明松桃道坨-冷水成锰沉积盆地和杨立掌-李家湾成锰沉积盆地为同一个成锰沉积盆地,深部找矿潜力较大。
Songtao manganese mining zone located in transition area of Yangtze block and Jiangnan block, crossed upper Yangtze block and Jiangnan orogenic belt. By comparison analysis of Datang formation layers in 7 manganese-forming sedimentary basins in this area, it＇ s thought the strata thickness of Datangpo formation has positive correlation with manganese grade and orebody thickness, the thicker of the Datangpo formation strata, the higher of manganese grade and the thicker of the orebody thickness. The grade has strong positive correlation with the thickness of the second and third section, the orebody thickness has strong positive correla- tion with the first section of Datangpo formation. Meanwhile, Datangpo formation and the change of manganese thickness shows Daotuo-Lengshui manganese-forming sedimentary basin has the same manganese-forming sedimentary basin with Yanglizhang-Lijiangwan manganese-forming sedimentary basin, the deep exploration potential is large.
