| 摘要: |
| 在渝东南地区中石炭统黄龙组中，发现了丰富的志留纪牙形刺化石，因此黄龙组必须解体为2个岩石地层单位。将志留系的地层新建立一个岩石地层单位—水江组。它是一套灰白～灰黄色细～微晶灰岩、白云质灰岩，时见重结晶现象和角砾状。与上覆石炭系黄龙组或二叠系梁山组假整合接触，下伏志留系韩家店组整合接触。 |

| Abstract: |
| In the southeast area of Chongqing Middle Carboniferous Huanglong Formation , found a wealth of Silurian conodont fossils, so the Huanglong Formation must be disintegrated into 2 .lithostratigraphic units.The Silurian strata will create a new lithostratigraphic unit---Shuijiang Formation. It is a Gray white--Pale yellow fine― microcrystalline limestone, calcareous dolomite, The Formation and the underlying Silurian Hanjiadian Formation conformity contact, and overlying the Carboniferous Huanglong Formation or Permian Liangshan Formation disconformable contact. |
