The Aghajari Formation, called also the Upper Fars, develops throughout the Folded Zagros Zone and its thickness in the type section in southwest of Iran is 2966 meters. To analyze the sedimentary basin of this Formation, lithofacies, architectural elements and petrofacies of the related deposits in a section in southeast of Sarvestan in Fars Province of Iran with a thickness of 2221.45 meters were examined. Microscopically studying thin sections, the petrography and the occurrence of the deposits were determined. In this section, 16 lithofacies, 10 architectural elements and 2 sandstone petrofacies were identified. The lithofacies were divided into two major and minor groups, in which the major lithofacies consist of coarse-grained （Gh, Gp, Gt and Gm）, medium-grained （Sh, Sp, St, Sl, Sm, Sr and Ss and fine-grained ones （Fm, Fl and Fsm）, and the minor lithofacies were evaporative and mixed silisiclastic-carbonate. The identified architectural elements are CH, SB, GB, LA, DA, CR, CS, LV, LS, CH （FF） and FF. By combining evidences from facies analysis and architectural elements together, the Aghajari Formation was divided into three parts in which the related sedimentation environments, from top to bottom, are gravel, gravel-sand and fine-grained meandering river respectively. There have also been playas and shoreface in the lower part. Based on petrography, the sandstones of this formation were classified into two groups： litharenite and sublitharenite. The origin of these deposits （sandstones） was appointed to the recycled orogeny and the source of quartz is low and medium to high metamorphic rank. Using the field evidences, the paleocurrent direction was achieved indicating the direction of the paleocurrent from northwest to southeast at the time of deposition. It is hoped that these data can be used in the interpretation of the basin and reconstruction of the paleogeography in the local and regional scales.

Facies analysis and depositional environments of the OligoceneeMiocene Asmari Formation, Zagros Basin, Iran

引用

Geoscience Frontiers 2014年第1期5卷 103-112页

作者： mohammad Sahraeyan mohammad bahrami Solmaz Arzaghi Department of Geology Khorasgan (Esfahan) Branch Islamic Azad UniversityEsfahan Iran Department of Geology Fars Science and Research Branch Islamic Azad UniversityShiraz Iran

The Asmari Formation （a giant hydrocarbon reservoir） is a thick carbonate sequence of the Oligocene Miocene in the Zagros Basin, southwest of h＇an. This formation is exposed at Tang-e-Lendeh in the Fars interior zone with a thickness of 190 m comprising medium and thick to massive bedded carbonates. The age of the Asmari Formation in the study area is the late Oligocene （Chattian）-early Miocene （Burdigalian）. Ten microfacies are defined, characterizing a gradual shallowing upward trend; the related environments are as follows： open marine （MF 8-10）, restricted lagoon （MF 6-7）, shoal （MF 3 5）, lagoon （MF 2）, and tidal fiat （MF 1 ）. Based on the environmental interpretations, a homoclinal ramp consisting of inner and middle parts prevails. MF 3-7 are characterized by the occmrence of large and small porcelaneous benthic foraminifera representing a shallow-water setting of an inner ramp, influenced by wave and tidal pro- cesses. MF 8-10, with large particles of coral and algae, represent a deeper fair weather wave base of a middle ramp setting.

Biostratigraphy and Paleoecology of Maastrichtian Sediments in the Zagros Basin, Iran

Acta Geologica Sinica(English Edition) 2013年第5期87卷 1387-1395页

作者： Mahnaz Parvaneh Nejad SHIRAZI Pegah SHAMS mohammad bahrami Department of Geology Payame Noor University Department of Geology Payame Noor University

To enable the lithostratigraphic and biostratigraphie study of the Gurpi Formation, within the ＇Dezak＇ or Globigerina Marl, a stratigraphic section at Booraki, located to the NNW of Shiraz, SW Iran, through the late Cretaceous was examined. The formation consists of shale and greenish-gray marls interbedded with cream limestone, brown sandstones and siltstones with an exposed thickness of 160 m in the studied section. Samples were taken at regular intervals in all yielding 14 genera and 16 different species of benthic and planktic foraminifera that allowed determination of the age of the beds as Maastrichtian. To examine the paleoecology of the formation, some important ecological factors including water level, salinity, and oxygen regime change during the depositional courses of the formation were analyzed. The density of foraminiferans decreases from the base to top of the Gurpi Formation whereas the ratio of planktic to benthic Foraminifera （i.e., P/B） and proportion of shallow-water fauna increase. These foraminiferal changes indicate an increase and decrease in depth, temperature, salinity and oxygen, respectively, at the base and top of the Formation.

Microfacies and Sedimentary Environments of the Fahliyan Formation from the Southwest of Iran (Shiraz, Zagros)

引用

Open Journal of Geology 2013年第2期3卷 49-53页

作者： Mahnaz Parvaneh Nejad Shirazi Fatemeh Dashtaby Jahromi mohammad bahrami Departement of Geology Payame-Noor University Tehran Iran

The Fahliyan Formation is a carbonate sequence of Lower Cretaceous (Berriasian-Hauterivian) in age and was deposited in the Zagros sedimentary basin. This formation is a part of Khami Group and is a reservoir rock in Zagros Basin. This formation was investigated by a detailed petrographic analysis in order to clarify the depositional facies and sedimentary environment in the Kuh-e-Gadvan in Fars Province. Petrographic studies led to the recognition of nine microfacies that were deposited in four facies belts: tidal flat, lagoon, and barrier and shallow open-marine. An absence of turbidite deposits, reefal facies, and gradual facies changes indicate that the Fahliyan Formation was deposited on a carbonate ramp.

BACKGROUND: According to the fact that women account for the highest rate of victims of mental health loss during disasters, prioritization of their requirements is of remarkable signifi cance. Therefore, the present study was carried out with the aim to prioritize factors related to women's mental health during an earthquake. METHODS: This study was conducted using the Delphi method in 2017. Participants consisted of experts including psychologists, counselors and psychiatrists, social medicine specialists, and psychiatric-mental health nurses with experience in service and disaster awareness, especially earthquake. They were selected using purposive and snowball sampling methods. The Delphi method was used in 2 rounds with 21 components and the fi nal attendance of 19 participants and the collective agreement of 75%. RESULTS: Of the 21 factors related to women's mental health during the earthquake, the following components were, respectively, preferred by the participants: psychological well-being training, group relationships and support of women in emergency situations, fair treatment in the provision of rights and services to women, crisis awareness and management of behavior and diffi cult conditions, and social security during disasters with the total mean standard deviation (SD) of 13.4 (2.4), 13.0 (2.4), 12.7 (2.5), 12.5 (2.4), and 12.3 (2.2), respectively. CONCLUSION: Training in the fi eld of psychology and disasters, and social and cultural factors were prioritized among factors related to women's mental health during an earthquake. Therefore, the results of this study can be applied by the planners and executives of mental health, women and disasters, and the women's community itself.

Stratigraphy of the Alveolina elliptica group from the Middle Eocene of Iran:Calibration with calcareous nannofossils biozones and description of Alveolina ozcani n. sp.

引用

Journal of Palaeogeography 2024年第1期13卷 54-79页

Precise taxonomy and the chronostratigraphic calibration of the Middle Eocene Alveolina from Central Iran is here undertaken from the Chah-Talkh section of the southern Sabzevar region(Central Iran). We have identified Alveolina kieli, Alveolina stercusmuris and Alveolina nuttalli along with the new species Alveolina ozcani n. sp. that we include into the Alveolina elliptica group. We have also found Nummulites uroniensis, Nummulites obesus and Nummulites cf. verneuili and associated calcareous nannofossils that look reliable to make thoughtful correlations with the Shallow Benthic Zones(SBZ). The foraminiferal biostratigraphy suggests an assignment to the upper part of the lower Lutetian-lower part of the middle Lutetian,SBZ13(Middle Eocene), further strengthened through the identification of the calcareous nannofossil NP14b-NP15b or CNE8-CNE10 biozones, providing a solid correlation with the global stratigraphic standards.
