چکیده
The Plio-Quaternary Ait Chaib basin occupies the northwestern part of Skoura Syncline, which is northern Middle Atlas Folded Zone. This intracontinental was formed probably in Pliocene after Tortono-Messinian regression sea. deposits are bound by fluvial conglomerates and continental carbonates. They consist barrage travertines; travertine limestones oncholitic silts sands upstream downstream deposits. These travertines laterally pass to lacustrine at bottom basin. genesis these carbonates, correlative phases karstification, has affected Meso-Cenozoic carbonate folded Atlas, linked favorable paleo-environmental conditions geological, geomorphological, hydrogeological, hydrological bioclimatic order. petrographic study shows laminar structure allowing assimilate into stromatolites. were cyanobacterial mats a shallow environment water non-turbid supersaturated limestone solution, coming from karstic springs staking out Atlasic North Accident. important diagenesis evolution surface table contain, as floor gypsiferous lagoonal marl Upper Miocene age.

The volcanic rocks with the Plio-Quaternary age, are exposed in the northern part of the Sanandaj-Sirjan zone, in northwest Urmia. The main mineral phases are olivin + clinopyroxene ± plagioclase, that are present as both phenocrysts to microcrystalline with other minor minerals. The dominant textures of these rocks are porphyry, microlithic porphyry, hyalo-porphyry, glomeroporphyritic and vesi...

abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...

In the southeast of Nir, south of Yazd Povince, several acidic volcanoes rocks are exposed and form the youngest volcanic rocks in this region with dacite-rhyodacite composition. These rocks are composed of plagioclase, hornblende, biotite and quartz phenocrysts with trachytic and hyallomicrolithic porphyry texture. Based on geochemical data, the magmatic affinity of these rocks is calc-alkali...
متن کاملMorphological differentiation of northern Morocco goat
Data from 183 animals raised in 61 flocks were collected to investigate the morphological characteristics of the Northern Morocco goat. Nine zoometric measures and seven combined indices were obtained. Three zones were defined based on geo-climatic characteristics and environmental influences: Mediterranean, Atlantic and Dual. The morphological variables showed the absence of sexual dimorphism...
