| 中文摘要:鹤庆小天井锰矿赋矿地层的时代，长期存在争论。有人将含锰地层归为上三叠统松桂组，也有人认为其属晚二叠世。本文根据前人资料及近年在该区取得的新成果，认为鹤庆小天井锰矿的赋矿地层属于晚二叠世。因此，在新一轮找矿突破战略行动中，应根据上二叠统地层的分布特点，来部署鹤庆地区锰矿的找矿工作。 |

| Abstract:There has long been a debate on the ore-bearing formation of Xiaotianjing Mn deposit in Heqing county. Some people classify the manganese-bearing strata as the Upper Triassic Songgui formation, while others believe that it belongs to the Late Permian. Based on the previous data and the new achievements made in this area in recent years, this paper considers that the ore formation of Xiaotianjing Mn deposit in Heqing belongs to the Late Permian. So, In the new round of prospecting breakthrough strategy action, Mn ore prospecting in Heqing area should be deployed according to the distribution characteristics of upper Permian strata. |
