introduction oolitic iron formations are sedimentary rocks with >5 vol.% oolites and >15 wt.% iron, corresponding to 21.4 wt.% fe2o3 (young, 1989; petranek and van houten, 1997; mucke and farshad, 2005). in iran, new iron oolite-bearing members have been identified in the lashkarak formation (lower-middle ordovician) in the abarsej, dehmola and simehkuh sections, eastern alborz (ghobadi pour et...

Fluoride concentrations in drinking water were analyzed relative to air temperature data collected in different provinces of Iran. Determining suitable concentrations of fluoride in drinking water is crucial for communities because of the health effects of fluoride on humans. This study analyzed fluoride concentrations in drinking water from selected Iranian provinces. The data were derived mai...

Existence of this gas in the mines not only creates a difficult and dangerous situation for work but also makes it more expensive. The release of this gas to the air causes a further ...

This study provides a multi-disciplinary overview of the seismology and geodetic data with tectonics analysis in order to provide an evaluation stress trajectories, probabilistic fault rupture hazard assessment. Based on different scenarios obtained from comparison several overviews their interpretation, we investigated kinematics active structural zones. In this study, magnitudes directions se...
