Abstract:To study the diagenesis of Gushan Formation in Dabeiwang profile, based on field profile and slice observation, the petrological characteristics and sedimentary environment of oolitic limetone in Gushan Forma-tion were studied and five typical diagenetic environment were summarized in combenation with the division of oolitic diversity analysis and diagenesis types and stages.The results show that the diagenesis types in Gushan Formation including cementation, dissolution, dolomitisation, dedolomitisation, compaction, recrystallization, metasomatism and so on;diagenesis stages including pene-sedimentary stage, early diagenetic stage, mid di-agenetic stage and eodiagenesis stage;under repeated and variation upward environment of gentle slope deposi-tional environment to high—energy shoal oolitic limestone sedimentary environment, Gushan Formation experi-enced meteoric diagenetic environment, marine diagenetic environment, mixed water diagenetic environment, burial diagenetic environment and surface diagenetic environment.
