| 摘要: |
| 在重庆市东南部，南华系只分布在秀山县和酉阳县，可细分为3个组：南沱组、大塘坡组和千子门组。其中南沱组和千子门组为冰碛层，沉积环境为低碛层、冰内河道相、冰前冰河相、冰前海湾泻湖相和冰前滨海相；大塘坡组为海湾泻湖相沉积，形成了大型锰矿床。区内南华纪气候具备典型的三段式结构特征：上、下两个冰期，中间夹一个间冰期，亦即南沱期、大塘坡间冰期和千子门期。 |

| Abstract: |
| In southeast Chongqing City,the Nanhuan System is only found in Xiushan and Youyang County and can be divided into three Formations:Nantuo Formations,Datangpo Formations and Qianzimen Formations,of which Nantuo Formations and Qianzimen Formations are Drift sheet,and their ssedimentary enviroment is glacial ground moraine-tillite facies,Lensatis sand-condlomerate facies in englacial channel,proglacial littora facies,forming a large managanese deposit,Nanhuan Period climate has the typical three-stage structural features:the upper and lower glacial,sandwhiched between an interglacial,i.e.Natuo glacia stage,the interglacial of Datangpo and Qianzimen glacial. |
