The Kamar-e-Mehdi Formation (Callovian – Oxfordian) is the fill of a shelf lagoon situated in the western and central parts of the so-called Tabas Block for a N-S distance of 200-300 km. From the predominantly fine-grained carbonates, which in the depocenter reach more than 1000 m in thickness, 69 taxa of bivalves are described, which differ greatly in their preservation depending on their orig...

high-cholesterol diet can be the fast track to a heart attack. But scientists are only now discovering that one of cholesterol’s most damaging effects might stem from its ability to make blood cells self-destruct. The findings appear in a pair of recent studies directed by Ira Tabas (Columbia University, New York, NY). Cholesterol is abundant in atherosclerotic lesions, which become most danger...

This study includes a thorough systematic analysis of the ichnological record in the Late Triassic siliciclastic Nayband Formation of the Tabas Block, Central Iran. A total of 48 ichnospecies representing 28 ichnogenera are identified and their preservation aspects, paleoecological aspects, producers and behavioral aspects are discussed. The ichnofauna includes Arenicolites, Asterosoma, Bergaue...

The TabaseColshan catastrophic earthquake of 16 September 1978 of magnitude M ~ 7 . 7 , the largest shock which has ever been recorded in Iran, occurred in Khorassan Province east central Iran (Fig. 1). The main shock took place in the evening, when most people were in their houses, at 19.38.18 local time (1535.58 GMT), without any felt foreshock. The preliminary instrumental epicentre is recor...

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...

Abstract Peat forming environment strongly influences the economic value of any coal seam and coal-bearing strata. Hence, palaeoenvironmental studies provide important information for resource exploration. In this context, detailed on selected coals from Parvadeh Area, Iran, were conducted using sedimentology, petrology, X-ray diffraction (XRD), scanning electron microscopy- energy dispersive a...

Background: Different bracing systems of steel Eccentric Braces (EBs) and steel-concrete Buckling-Restrained (BRBs) can be used in frames order to make the stronger resisting lateral loads. These with EBs or BRBs are generally called Eccentrically Braced Frames (EBFs) (BRBFs), respectively. Objective: This study aims investigate having moment link. Methods: The EBFs BRBFs nonlinearly analysed e...

Abstract The Garedu Red Bed Formation (GRBF) of the northern Tabas Block (Central-East Iranian Microcontinent, CEIM) is a lithologically variable, up to 500-m-thick, predominantly continental unit. It rests gradually or unconformably on marine limestones Esfandiar Subgroup (Callovian–Oxfordian) and assigned Kimmeridgian–Tithonian. In lower part, it consists pebble- boulder-sized conglomerates/b...
