Before 1991, the states of Central Asia were marginal backwaters, republics of the Soviet Union that played no major role in the Cold War relationship between the USSR and the United States, or in the Soviet Union’s relationship with the principal regional powers of Turkey, Iran, and China. But, in the 1990s, the dissolution of the Soviet Union coincided with the re-discovery of the energy reso...

The study area is located in the western portion of Isfahan, in Shahrekord-Dehsard Terrene. This area is part of the Sanandaj- Sirjan structural Zone. In this area, metamorphosed igneous outcrops contain greenschist and metabasite rocks. These rocks have metamorphed into greenschist facies and belong to the Triassic-Jurassic age. The etabasite is mainly composed of plagioclase, amphibole, epido...

BACKGROUND Hyalomma anatolicum is the well-known hard tick, which is one of the most important livestock and human pathogens vector, wide range in host and distributed in all over the Hyalomma geographic fauna as well as in Iran. Taxonomy of the Hyalomma ssp. is debatable whereas their identification is a problematic work. The reasons for this claim is time consuming Delpy's researches in Iran ...

Many abnormal α-chain hemoglobins (Hbs) are caused by single nucleotide mutations in α1- or α2-goblin genes. One of these Hbs is Hb Q-Iran which is resulted from a point mutation at codon 75 of the α1-globin gene (Asp→His). The identification of Hb Q-Iran was observed in two members of a family from the Central Province of Iran. In this study, Globin chain analysis on high performance liquid ch...

The Haft Saravan area is located in 90 km SE Arak in the central Iran. This area is a part of Malyer-Isfahan metallogenic belt. The article's objective is determining the most suitable method for identifying mineralized zones using original singularity and weighted singularity methods in three-dimensional space. In weighted singularity method, mineralized zones have a greater volume relative to...

The aim of this work is to propose a first-order estimate of the crustal and lithospheric mantle geometry of the Arabia–Eurasia collision zone and to separate the measured Bouguer anomaly into its regional and local components. The crustal and lithospheric mantle structure is calculated from the geoid height and elevation data combined with thermal analysis. Our results show that Moho depth var...

Biostratigraphy of Oligo-Miocene marine deposits Central Iran basin based on calcareous nannoplanktons

Raveniola niedermeyeri (Brignoli, 1972), a poorly known species, is rediagnosed and redescribed from the types and from recently collected material from northern and central regions of Iran. This species differs from its congeners in having the male embolus curved distally, as well as in the unique conformation of the spermathecae. New data on the distribution of Raveniola niedermeyeri in Iran ...
