rhaetian strata from the nayband formation of the tabas block, east- central iran, were studied palynologically. the materialexamined contained moderately diverse and well-preserved dinoflagellate cyst assemblages which lead to the identification ofrhaetogonyaulax rhaetica zone. the assigned age of this dinozone (rhaetian) is justified by plant fossils such as equisetitesarenaceus, scytophyllum...

Abstract New detrital U–Pb zircon ages from the Sanandaj–Sirjan metamorphic zone in Zagros orogenic belt allow discussion of models late Neoproterozoic to early Palaeozoic plate tectonic evolution and position Iranian microcontinent within a global framework. A total 194 valid age values 362 grains were obtained three garnet-micaschist samples. The most abundant population included Ediacaran ag...

Active deformation in Alborz range is due to N-S convergence between Arabia and Eurasia. This paper provides geomorphic traces of regional deformation in NW Iran in order to characterize active faulting on major faults. Soltanieh and North Zanjan fault systems are involved in convergence boundary extent between South Caspian Basin and Central Iran. Soltanieh and North Zanjan faults are major re...

In order to survey the evolutionary history and impact of historical events on the genetic structure of Iranian people, the HV2 region of 141 mtDNA sequences related to six Iranian populations were analyzed. Slight and non-significant FST distances among the Central-western Persian speaking populations of Iran testify to the common origin of these populations from one proto-population. Mismatch...

In this paper, by using combination of molecular and chromosomal markers, populations of Polyommatus (Agrodiaetus) karindus (Riley, 1921) from north-west and central Iran are analyzed. It has been found that taxon usually identified as Polyommatus (Agrodiaetus) karindus is represented in Iran by two geographically separated groups of individuals, strongly differentiated by their karyotypes and ...

In the Cenomanian, southern passive margin of Neotethys Ocean was dominated by a giant carbonate factory. This succession is known as Sarvak Formation, significant reservoir in Iran. study focuses on detailed analysis facies variations and paleoenvironmental reconstruction, including interpretation platform types, during this time interval. Based field observations petrographical studies, 12 ha...

the halak abad prospect occurs in the northeastern part of central iran zone (sabzevar structural zone). in this investigation, geochemical evolution, age and source of part of northeastern iran magmatic arc (intrusive bodies) in halak abad area in the khorasan razavi province has been studied. the exposed rocks consist of volcanic rocks with andesite and dacite nature, limestone, plutonic rock...
