| 1 | Geochemistry of Carboniferous Sandstones (Sardar Formation), East-Central Iran: Implication for Provenance and Tectonic Setting显示文摘Geochemical analysis of sandstones from the Sardar Formation (from two stratigraphic successions) in east-central Iran were used for identification of geochemical characterization of sandstones, provenance and tectonic setting. Sandstones in the two lithostratigraphic successions have similar chemical compositions suggesting a common provenance. Bulk-rock geochemistry analysis of Carboniferous sandstones from Sardar Formation indicates that they are mainly quartz dominated and are classified as quartzarenites, sublitharenites and subarkoses, derived from acid igneous to intermediate igneous rocks. Discrimination function analysis indicates that the sandstones of Sardar Formation were derived from quartzose sedimentary provenance in a recycled orogenic setting. Also, major and trace elements in sandstones of Sardar Formation (e.g., K 2 O/Na 2 O vs. SiO 2 ) indicate deposition in a stable passive continental margin (PM). Chemical index of alteration (CIA) for these rocks (>65%) suggests a moderate to relatively high degree of weathering in the source area. | Mohammad KHANEHBAD Reza MOUSSAVI-HARAMI Asadollah MAHBOUBI Mehdi NADJAFI Mohammad Hosein MAHMUDY GHARAIE | 2012 | Acta Geologica Sinica(English Edition)2012，86，5： | 7 |
| 2 | Discrete simulation and micromechanical analysis of two-dimensional saturated granular media显示文摘In this study,a novel approach to incorporate the pore water pressure in the discrete element method(DEM) to comprehensively model saturated granular media was developed.A numerical model was constructed based on the DEM by implanting additional routines in the basic DEM code;pore water pressure calculations were used with a two-dimensional(2D) model to simulate the undrained behavior of saturated granular media.This model coupled the interaction of solid particles and the pore fluid in saturated granular media.Finally,several 2D undrained shear tests were simulated.The test results showed that the model could predict the response of the saturated granular soil to shear loading.The effect of initial compaction was investigated.Biaxial tests on dense and loose specimens were conducted,and the effect of the initial density on the change in shear strength and the volume change of the system was investigated.The overall behavior of loose and dense specimens was phenomenologically similar to the real granular material.Constant volume tests were simulated,and the results were compared to those from the coupled model.Induced anisotropy was micromechanically investigated by studying the contact force orientation.The change in anisotropy depended on the modeling scheme.However,the overall responses of the media obtained using the coupled and constant volume methods were similar. | Younes Khalili Ahmad Mahboubi | 2014 | Particuology2014，12，4： | 5 |
| 3 | Provenance, Tectonic Setting and Geochemistry of Ahwaz Sandstone Member(Asmari Formation, Oligo-Miocene), Marun Oilfield, Zagros Basin, SW Iran显示文摘The Asmari Formation deposited in the Zagros foreland basin during the OligoceneMiocene. Lithologically, the Asmari Formation consists of limestone, dolomitic limestone, dolomite, argillaceous limestone, some anhydrite(Kalhur Member) and sandstones(Ahwaz Member). This study is based on the analysis of core samples from four subsurface sections(wells Mn-68, Mn-281, Mn-292 and Mn-312) in the Marun Oilfield in the Dezful embayment subzone in order to infer their provenance and tectonic setting of the Ahwaz Sandstone Member. Petrographical data reveal that the Ahwaz Sandstone comprises 97.5% quartz, 1.6% feldspar, and 0.9% rock fragments and all samples are classified as quartz arenites. The provenance and tectonic setting of the Ahwaz Sandstone have been assessed using integrated petrographic and geochemical studies. Petrographic analysis reveals that mono- and poly-crystalline quartz grains from metamorphic and igneous rocks of a craton interior setting were the dominant sources. Chemically, major and trace element concentrations in the rocks of the Ahwaz Sandstone indicate deposition in a passive continental margin setting. As indicated by the CIW′ index(chemical index of weathering) of the Ahwaz Sandstone(average value of 82) their source area underwent 'intense' recycling but 'moderate to high' degree of chemical weathering. The petrography and geochemistry results are consistent with a tropical, humid climate and low-relief highlands. | Shahram AVARJANI Asadollah MAHBOUBI Reza MOUSSAVI-HARAMI Hassan AMIRI-BAKHTIAR | 2014 | Acta Geologica Sinica(English Edition)2014，88，3： | 4 |
| 4 | A worldwide SPT-based soil liquefaction triggering analysis utilizing gene expression programming and Bayesian probabilistic method显示文摘In this context,two different approaches of soil liquefaction evaluation using a soft computing technique based on the worldwide standard penetration test(SPT) databases have been studied.Gene expression programming(GEP) as a gray-box modeling approach is used to develop different deterministic models in order to evaluate the occurrence of soil liquefaction in terms of liquefaction field performance indicator(LI) and factor of safety(F_S) in logistic regression and classification concepts.The comparative plots illustrate that the classification concept-based models show a better performance than those based on logistic regression.In the probabilistic approach,a calibrated mapping function is developed in the context of Bayes' theorem in order to capture the failure probabilities(P_L) in the absence of the knowledge of parameter uncertainty.Consistent results obtained from the proposed probabilistic models,compared to the most well-known models,indicate the robustness of the methodology used in this study.The probability models provide a simple,but also efficient decision-making tool in engineering design to quantitatively assess the liquefaction triggering thresholds. | Maral Goharzay Ali Noorzad Ahmadreza Mahboubi Ardakani Mostafa Jalal | 2017 | Journal of Rock Mechanics and Geotechnical Engineering2017，9，4： | 3 |

| 6 | Facies Analysis and Sequence Stratigraphy of Silurian Carbonate Ramps in the Turan(Kopeh-Dagh) and Central Iran Plates with Emphasis on Gondwana Tectonic Event显示文摘Two sections from the Silurian deposits in the Central Iran Micro and Turan Plates were measured and sampled. These deposits are mostly composed of submarine volcanic rocks, skeletal and non-skeletal limestone, shale and sandstone that were deposited in low to high energy conditions(from tidal flat to deep open marine). According to gradual deepening trend, wide lateral distribution of facies as well as absence of resedimentation deposits, a depositional model of a homoclinal ramp was proposed for these deposits. Field observations and facies distribution indicate that, two depositional sequences were recognized in both sections. These sections show similarities in facies and depositional sequence during the Early Silurian in the area. Although there are some opinions and evidences that demonstrated Paleo-Tethys rifting phase started at the Late Ordovician-Early Silurian, similarities suggest that the Turan and Iran Plates were not completely detached tectonic block during this time, and that their depositional conditions were affected by global sea level changes and tectonic events. | Zohreh NOWROUZI Asadollah MAHBOUBI Reza MOUSSAVI-HARAMI Mohammad Hossein MAHMUDY GHARAIE Farzin GHAEMI | 2015 | Acta Geologica Sinica(English Edition)2015，89，4： | 2 |
| 7 | Facies Analysis and Sequence Stratigraphy of the Qal'eh Dokhtar Formation(Middle-Upper Jurassic) in the West of Boshrouyeh, East Central Iran显示文摘The study area is located in the east Tabas Block in Central Iran. Facies analysis of the Qal'eh Dokhtar Formation(middle Callovian to late Oxfordian) was carried out on two stratigraphic sections and applied to depositional environment and sequence stratigraphy interpretation. This formation conformably overlies and underlies the marly-silty Baghamshah and the calcareous Esfandiar formations, respectively. Lateral and vertical facies changes documents low-to high energy environments, including tidal-flat, beach to intertidal, lagoon, barrier, and open-marine. According to these facies associations and absence of resedimentation deposits a depositional model of a mixed carbonate-siliciclastic ramp was proposed for the Qal'eh Dokhtar Formation. Seven third-order depositional sequences were identified in each two measured stratigraphic sections. Transgressive systems tracts(TSTs) show deepening upward trends, i.e. shallow water beach to intertidal and lagoonal facies, while highstand systems tracts(HST) show shallowing upward trends in which deep water facies are overlain by shallow water facies. All sequence boundaries(except at the base of the stratigraphic column) are of the no erosional(SB2) types. We conclude eustatic rather than tectonic factors played a dominant role in controlling carbonate depositional environments in the study area. | Mahnaz SABBAGH BAJESTANI Asadollah MAHBOUBI Reza MOUSSAVI-HARAMI Ihsan AL-AASM Mehdi NADJAFI | 2017 | Acta Geologica Sinica(English Edition)2017，91，5： | 2 |
