dalichai formation at the rey-abad section (northeast shahroud) along the principal road of the mayamey-jajarm has a thickness of 166 meters .in this section, middle to upper jurassic carbonate rocks are well exposed and is typically composed of massive to medium-bedded limestones with thin shale interbeds. in the studied area and most places of this region, the lower boundary of dalichai forma...
Palynological and Palynofacies analysis combined with sedimentological studies have been performed on Dalichai Formation, northeast of Semnan, in order to define its paleoenviromental interpretation. Based on petrographic studies of organic matter, three palynofacies types were recognized as PF-1, PF-2, and PF-3. PF-1 is a characteristic of proximal shelf settings or basin. This palynofacies in...
in order to determine the dalichai formation paleoecology (middle jurassic), with measured thicknesses of 255 m at bar section, nw neyshabour, 28 samples systematically were collected. based on 112 palynological slides studies, 29 species of spore and pollen, which belong to 21 genera, have been identified. in addition to spores and pollens, dinoflagellate and fungus bodies form the palynomorph...
this research concentrates on the lithostratigraphy, biostratigraphy, microfacies and sedimentary environment of the asmari and gachsaran formations at southwest firuzabad. the thickness of the studied section in all 608.95 meters that 220.8 meters belong to the asmari formation and 387.95 meters belong to the gachsaran formation (champe and mol members). in the study area, the asmari formation...
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
this study investigated how group formation method, namely student-selected vs. teacher-assigned, influences the results of the community model of teaching creative writing; i.e., group dynamics and group outcome (the quality of performance). the study adopted an experimental comparison group and microgenetic research design to observe the change process over a relatively short period of time. ...
dans le monde où l’homme est l’élément le plus important de la vie, la formation de nouvelles générations a une importance particulière. en rédigeant emile, jean jacques rousseau, exerce une influence extraordinaire sur la vie humaine et mène à réfléchir sur la question de l’éducation en tant qu’un art. ce penseur du xviiie siècle, grâce à son élève imaginaire, emile, présente son idéal pédagog...
در این پژوهش به منظور درک سن و محیط رسوبی سازند آسماری در برش کوه شجبیل، شمال غرب یاسوج به ضخامت 375 متر 171 نمونه برداشت گردیده است. سازند آسماری در برش مورد مطالعه با معیارهای سنگ شناختی به سه واحد مشخص تفکیک شده است. این واحد ها با داشتن شمای آهک های مسیو، ضخیم، متوسط و نازک لایه، آهک های نازک لایه ی مارنی و بعضاً مارن مشخص می گردد. در این برش تعداد 18 جنس و 29 گونه از فرامینیفرهای بنتیک شنا...
