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...

Based on the importance and role of species diversity and richness as ameasurement of the health of an ecosystem; studying of their components can lead toevaluate the health condition of rangeland. This research was carried out in a part ofhighland mountainous rangeland of Mount Alborz Range in Iran. Diversity and richnesswere assessed as an ecosystem health indicator. The study area was locate...

in the present study, the q factor is obtained for the central alborz in iran using the lg coda method. the energy of a seismic wave decays while passing through a ‘real’ medium such as the earth which is not completely elastic. the decay in energy is due to non-elastic phenomena and is called intrinsic attenuation and is characterized with the q parameter, the large values of which represent s...

surface oil seeps from alasht, lapur and jenesem share many compositional affinities including distributions and concentrations ofnormal alkanes, terpanes and steranes. these oils also show many similarities with that of jurassic sediments (shemshak group, klarizformation) systematically sampled from the galandrud coal mine. recent geochemical studies in this area indicated that theshemshak gro...
