| 摘 要： | 老龙锰矿是近几年来,在广南地区下泥盆统芭蕉箐组碳酸盐岩系中新发现的沉积型锰矿,研究表明,早泥盆世晚期,连同广南地区在内的广大区域地壳大幅度沉降,海水变深,浮游生物等大量死亡,并伴有锰矿沉积,芭蕉箐组中的硅质岩为锰矿层的顶底板,是该锰矿的直接找矿标志.

| Abstract: | Laolong Mn deposit is a sedimentary Mn deposit discovered in Lower D Bajiaoqing Formation car- bonate rock series in Guangnan area in recent years. The study shows the large dimension sinking of crust, sea water deepening, the death of large amount of planktons and the associated Mn deposit in the wide area of Guang- nan region during the late period of early D. The top and bottom of Mn ore bed are Bajiaoqing Formation silicie rocks, which are the direct prospecting criteria of this Mn deposit. |
