| 摘 要： | 贵阳乌当地区上奥陶统碳酸盐岩地层与扬子地区同时代地层相比具有其特殊性,黄花冲组与宝塔组"龟裂纹"灰岩时代相当.通过对该地区中、上奥陶统碳酸盐岩的研究,划分出亮晶生屑灰岩相、泥晶生屑灰岩相、含生屑泥晶灰岩相、生屑泥晶灰岩相和页岩-粉砂岩相5种沉积相;根据沉积相组合推断此时期乌当地区黄花冲组处于局限潮下低能环境.

| Abstract: | The Late Ordovician carbonates in Wudang,Guiyang differ from the coev al sediments at other sections in Yangtze area.Based on the study of the Middle and Late Ordovician in Wudang,in combination with analysis on sedimentary facies,it is deduced that the Huanghuachong formation was formed in restricted subtid al environments.Five sedimentary facies have been distinguished,i.e.skeletal grainstone,skeletal packstone,skeletal wackestone,lime mudstone and shale-siltstone facies. |

| Keywords: | Middle and Upper Ordovician lithofacies sedimentary environment Wudang of Guiyang |
