Hezar complex is a part of Dehaj-Sarduiyeh volcano-plotunic belt in southwest of Rayen (Kerman province). Investigations on lava flows show that they have basalt, basaltic-trachy-andesite, trachy-andesite ,and trachy-basalt composition. On the basis of petrographic studies, the rocks contain plagioclase (Oligoclase - Andesine), pyroxene (Augite - Diopside) and much altered olivine. Plagioclases...

The most important features and phenomena of the deformation behavior of rockfills are stress-dependent stiffness, hardening and dilative (or contractive) behaviors, as well as breakage, rotation and redistribution of particle size. An elasto-plastic constitutive model has been suggested by Vermeer and de Borst to simulate the shear behavior of soils, concretes and rocks. This research has trie...

Eocene- Oligocene volcanic and subvolcanic bodies of Masjed-Daghi Located in 35 km East of Jolfa close of Aras River. On the base of structural geology the study area is a part of the West Alborz-Azarbayejan zone. Volcanic rocks are rhyolite, dacite to trachyandesite and subvolcanic rocks are porphyritic monzonite to diorite. The Formation of these rocks related to  subduction zone in an active...
