| Abstract: | Anshun formation is dolomite association between Dayi formation and Guanling formation,it＇s divided into 3 lithologies,and the sedimentary dolomite is introduced as the key point.According to the relevant theory of petrology and sedimentation,the sedimentary environment and its evaluation of Anshun formation is studied,this formation is thought to be the limited carbonate platform sediment.From the bottom to the top,it experienced the evaluation： the platform margin shoal in the first stage,the tidal zone to supratidal zone in the second stage and the supratidal zone in the third stage,then the Qianzhong carbonate platform and its sedimentary situation of trailing edge gentle slope is formed. |
