| Abstract: | A study of depositional characteristics on carbonate rocks of Permo-Carboniferous was carried out by analyzing of petrology and their formation characteristics of carbonate rocks. A lot of fieldworks of the Permo-Carboniferous system in the study area indicate that,the carbonate rocks of Permo-Carboniferous are dominated by calcirudite,crinoidal limestone and micrite with massive structure and graded bedding,volcanic or pyroclastic rocks acting as pedestals and interbeds of the carbonate formations prevail ... |
