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...

The genus Tropiocolotes comprises small, naked toed, ground dwelling and nocturnal desert geckos, ranging from Morocco and Mauritania in northern Africa to south and central Arabia as well as coastal Iran. Herein, we describe a new species of the genus Tropiocolotes from western Iran based on five specimens from Nayband region. This new taxon is described with a statistical approach based on 34...

Introduction: Cadmium (CD) and lead (Pb) are widely used in the industrial and refining activities and are frequently detected in sediments. The main objectives of this research were focused on determining the concentration of Cd and Pb in the sediments of Asaluyeh and compare them with other parts of the world. Materials and Methods: The concentrations of Pb and Cd in the sediments of Nayband ...

the sorkh shale formation (lower triassic) crops out in parts of tabas block. this formation is composed of limestone, dolomite, sandstone, shale and gypsum. its lower contact with the permian rocks and its upper contact with the shotori formation is marked by distinct erosional unconformity. to determine the depositional environments of the sorkh shale formation, stratigraphic sections of goda...

Polycyclic aromatic hydrocarbons (PAHs) biodegradation in contaminated sediment is an attractive remediation technique and its success depends on the optimal condition for the PAH-degrading isolates. The aims of the current study was to isolate and identify PAHs-degrading bacteria from surface sediments of Nayband Bay and to evaluate the efficiency of statistically based experimental design for...

Qadir Member of Nayband Formation, located in East Central Iran, has developed to a great extent. Investigation the lithofacies and sedimentary environment, resulted identification deltaic marine deposits. Based on field evidence facies features, consists two lithofacies, including carbonate siliciclastic facies. The were identified as having four sandstone Sr, Sh, Sp, St, three fine-grained FI...
