Bauxite deposit of Permo-Triassic age in northeast of Bukan was developed stratiformly along the boundary between Ruteh and Elika formations, and includes four distinct rock units. This deposit was affected by tectonic and morphological processes. Mineralogical and geochemical investigations showed that during weathering processes, two mechanisms of ferrugenization and deferrugenization played ...
biglar permo-triassic bauxite deposit is located in ~15 km northwest of abgarm, southwest of ghazvin province, west of central iran. it consists of 8 stratiform and discontinuous bauxite lenses lying along the contact of ruteh (permian) and elika (triassic) carbonate formations. petrographically, the bauxite ores exhibit collomorphic-fluidal, pseudo-breccia, pseudo-porphyritic, panidio-morphic-...
the gheshlagh bauxite deposit is located 110 km southeast of gorgan. the deposit has been developed as a stratiform horizon with more than 2 km length and a thickness of about 25 m along the contact of ruteh and elika carbonate formations. textural analysis indicates both allochthonous and autochtonous origins for the bauxites. bohemite, diaspore, anatase, rutile, hematite, goethite, kaolinite,...

Aghadjari bauxite deposit is located in ~15km south of Shahindezh, West-Azarbaidjan province. This deposit was developed as stratiform lenses along the contact of Rutheh and Elika carbonate formations. Bauxitization processes led to the formation of boehmite, diaspore, kaolinite, pyrophyllite, illite, hematite, goethite, anatase, rutile, and quartz. Ferrugenization and deferrugenization mechani...
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...

The Qopi bauxitic horizon is located west of Miandoab, in West-Azarbaidjan province, NW of Iran. It lies along the boundary of Ruteh (middle-upper Permian) and Elika (lower Triassic) Formations. This horizon includes four distinct lithologic facies such as (1) bauxitic iron ore, (2) ferruginous bauxite, (3) Fe-rich bauxite, and (4) Fe-rich clayey bauxite. Microscopic examinations showed variou...
