HIGH RESOLUTION SEQUENCE STRATIGRAPHY AND DIAGENESIS IN CARBONATE ROCKS,WONOSARI FORMATION,YOGYAKARTA:AN OUTCROP ANALOG FOR MODELING CHALKY LIMESTONE RESERVOIR DISTRIBUTION

摘要

The importance of outcrop data in the development of carbonate sequence stratigraphy and diagenesis is highlighted by a study of the Middle Miocene carbonate of the Wonosari Formation,Yogyakarta.Four carbonate sequences are studied for use as analogs to model the distribution of chalky limestone reservoirs.Depositional and diagenetic facies have been correlated allowing a model of facies development and chalky limestone genesis and distribution in response to relative sea level changes to be reconstructed for the study area.
