AbstractDiagenesis were studied within Khurmala limestone Formation at Dokan area, Northeastern Iraq. The study recognized many diagenetic processes
affected limestone within a successive sequence including micrite envelope, dolomitization, dissolution, neomorphism, cementation, mechanical and chemical compaction. The study determined four diagenetic zones. They are marine zone (micrite envelope), mixing zone (dolomitization), meteoric pheratic zone (dissolution, neomorphism, cementation) and burial zone (mechanical and chemical compaction). According to the history of diagenesis and their sequence, the study revealed that periodical fluctuation in sea level has influenced on diagenetic processes and their paragenetic sequence.
