Jurassic deposits are well exposed in the Bazehowz area, South west of Mashhad city, East Alborz, Iran. It contains plant macrofossilsbelonging to eighteen species of eleven genera of various orders such as Equisetales, Filicales, Bennettitales, Cycadales,Corystospermales, Caytoniales, Ginkgoales and Pinales. Two biozones were recognized in the type section of Bazehowz Formation.Biozone I is an...

The trace fossil assemblages from the Unit 2 of Deh-Sufiyan Formation are described for the first time from The Central Alborz Range of northern Iran,  improving the record of the assemblages in the Cambrian of the Middle East. Twenty-one ichnogenera have been identified in the Deh-Sufiyan Formation, namely Arenicolites, Bergaueria, Chondrites, Circulichnus, Cruziana, Diplichnites, Didymaulichnu...

Climate is one of the many factors such as socio-cultural values, economics, materials,administrative factors and technology that influence architectural forms. The climatic solutions effecting on architecture,differ in various regions, cultures, time and technology. The climate of the province of Golestan plays an active rolein the formation and diversity of vernacular dwellings. This region i...

Abundance and multilateral extension of prominent genus and species of Brachiopoda in the majority of sedimentation series of the Late Devonian have been observed in all parts of Iran. The variability and rapid change in this respect has made it possible to delineate different lines of orthogenetism, biozonation and present biostratigraphical models at the sub-stage level. These characteristics...

Probabilistic seismic hazard analysis, as the most prevalent approach to evaluate earthquake hazard, is commonly based on catalogs. Although previous studies show that recurrence time of large-magnitude (Mw> 7.0) events in Iran more than ~ 1000–2000 years, available instrumentally recorded earthquakes are limited less 100 years. With idea having another proxy for seismicity rates, we propose a ...
