| 1 | Cyclic Sequences, Events and Evolution of the Sino-Korean Plate, with a Discussion on the Evolution of Molar-tooth Carbonates, Phosphorites and Source Rocks显示文摘This paper gives an account of the research that the authors conducted on the cyclic sequences, events and evolutionary history from Proterozoic to Meso-Cenozoic in the Sino-Korean plate based on the principle of the Cosmos-Earth System. The authors divided this plate into 20 super-cyclic or super-mega-cyclic periods and more than 100 Oort periods. The research focused on important sea flooding events, uplift interruption events, tilting movement events, molar-tooth carbonate events, thermal events, polarity reversal events, karst events, volcanic explosion events and storm events, as well as types of resource areas and paleotectonic evolution. By means of the isochronous theory of the Cosmos-Earth System periodicity and based on long-excentricity and periodicity, the authors elaborately studied the paleogeographic evolution of the aulacogen of the Sino-Korean plate, the oolitic beach platform formation, the development of foreland basin and continental rift valley basin, and reconstructed the evolution of tectonic paleogeography and stratigraphic framework in the Sino-Korean plate in terms of evolutionary maps. Finally, the authors gave a profound discussion on the formation and development of molar-tooth carbonates, phosphorites and source rocks. | MENG Xianghua and GE MingInstitute of Sedimentary Basin, China University of Geosciences, Beijing 100083 E-mail: mengxh@cugb.edu.cn Liu Xinzhu and Zhu Xiling | 2003 | Acta Geologica Sinica(English Edition)2003，77，3： | 17 |

| 5 | Facies and Depositional Sequences of the Asmari Formation, Shajabil Anticline, North of the Izeh Zone, Zagros Basin, Iran显示文摘Outcrop and microscopic studies have been applied in this research paper in order to find out the Asmari Formation depositional sequences in the Shajabil Anticline section located at the north of the Izeh Zone,Zagros Basin,Iran.Five depositional sequences were identified based on 11 facies types(bioclast Nummulitidae Lepidocyclinidae packstone,bioclast perforate foraminifera Nephrolepidina Miogypsinoides wackestone-packstone,bioclast perforate foraminifera Corallinacea wackestone-packstone,bioclast echinoid Neorotalia Brachiopoda wackestone-packstone,coral floatstone-rudstone,bioclast Corallinacea imperforate foraminifera wackestone-packstone,bioclast imperforate foraminifera Archaias wackestone-packstone,bioclast imperforate foraminifera Dendritina wackestone-packstone-grainstone,bioclast imperforate foraminifera Borelis wackestonepackstone and very fine sandy mudstone)corresponding to the tidal flat,restricted and semirestricted lagoon and open marine environments of an inner and middle shelf areas.Well-exposed outcrop horizons of Thalassinoides at the study section are a favorable tool for the regional outcrop sequence stratigraphy.Thalassinoides is considered as an outcrop key-bed for recognition of the Rupelian-Chattian maximum flooding depositional sequence.Coral remnants(small colonies)in outcrop exposures also are associated with the HST depositional sequence(Chattian)for the Asmari Formation.The most important achievement of this research is use of associated maximum flooding surfaces(Pg30,Pg40,Pg50,Ng10 and Ng20)in the Arabian plate.These maximum flooding surfaces could be recorded as an isochrones surface. | Zahra SALEH Ali SEYRAFIAN | 2013 | Acta Geologica Sinica(English Edition)2013，87，6： | 3 |
| 6 | Genetic mechanism and development of the unsteady Sarvak play of the Azadegan oil field,southwest of Iran显示文摘The upper Cretaceous Sarvak reservoir in the Azadegan oil field of southwest Iran has its oil–water contact nearly horizontal from the north to the center and dips steeply from the center to the south.The purpose of this paper is to interpret this abnormal reservoir feature by examining the accumulation elements,characteristics,and evolution based on the 3D seismic,coring,and well logging data.Generally,in the field,the Sarvak reservoir is massive and vertically heterogeneous,and impermeable interlayers are rare.The distribution of petrophysical properties is mainly dominated by the depositional paleogeomorphology and degrades from north to south laterally.The source is the lower Cretaceous Kazhdumi Formation of the eastern Dezful sag,and the seal is the muddy dense limestone of the Cenozoic Gurpi and Pebdeh Formations.Combined with the trap evolution,the accumulation evolution can be summarized as follows: the Sarvak play became a paleo-anticlinal trap in the Alpine tectonic activity after the late Cretaceous(96 Ma) and then was relatively peaceful in the later long geologic period.The Kazhdumi Formation entered in the oil window at the early Miocene(12–10 Ma) and charged the Sarvak bed,thus forming the paleo-reservoir.Impacted by the ZagrosOrogeny,the paleo-reservoir trap experienced a strong secondary deformation in the late Pliocene(4 Ma),which shows as the paleo-trap shrank dramatically and the prelow southern area uplifted and formed a new secondary anticline trap,hence evolving to the current two structural highs with the south point(secondary trap) higher than the north(paleo-trap).The trap deformation broke the paleoreservoir kinetic equilibrium and caused the secondary reservoir adjustment.The upper seal prevented vertical oil dissipation,and thus,the migration is mainly in interior Sarvak bed from northern paleo-reservoir to the southern secondary trap.The strong reservoir heterogeneity and the degradation trend of reservoir properties along migration path(north to south) made the reservoir readjustment extremely slow,plus the short and insufficient re-balance time,making the Sarvak form an ‘‘unsteady reservoir''which is still in the readjustment process and has not reached a new balance state.The current abnormal oil–water contact versus the trap evolutionary trend indicates the secondary readjustment is still in its early stage and has only impacted part of paleo-reservoir.Consequently,not all of the reservoir is dominated by the current structure,and some parts still stay at the paleo-reservoir form.From the overview above,we suggest the following for the future development: In the northern structural high,the field development should be focused on the original paleoreservoir zone.In the southern structural high,compared with the secondary reservoir of the Sarvak with the tilted oil–water contact and huge geologic uncertainty,the lower sandstone reservoirs are more reliable and could be developed first,and then the deployment optimized of the upper Sarvak after obtaining sufficient geological data.By the hints of the similar reservoir characteristics and tectonic inheritance with Sarvak,the lower Cretaceous Fahliyancarbonate reservoir is also proved to be an unsteady reservoir with a tilted oil–water contact. | Yang Du Jie Chen Yi Cui Jun Xin Juan Wang Yi-Zhen Li Xiao Fu | 2016 | Petroleum Science2016，13，1： | 3 |
