the eocene volcanic rocks from the southwest of the jandaq (kuh-e-godar-e-siah, central-east iran micro-continent) are andesitic basalt and andesite in composition. these rocks contain xenoliths with granulitic mineralogy. mineral assemblage of these xenoliths is plagioclase + phlogopite + corundum + sillimanite + chlorite + phengite with granublastic, poiklioblastic and foliated textures in th...

cambrian sediments are widely exposed in the kerman province. parts of these deposits are containing trilobite fossils. one of the suitable areas for paleontological studies is kamar siah section. this section located about 60 km north east of kerman. these sediments have 200 m thickness with fossil invertebrates of trilobites, brachiopod, gastropods and stromatolite which includes kuhbanan and...

A total of five specimens of Allactaga hotsoni were captured in Khorasan and Yazd provinces, Iran, in summer 2004 and 2005. The specimens are similar to those described previously from Baluchistan of Iran and Afghanistan. For the first time a karyological study was carried out to make a comparison with the other species. On the basis of karyological study there is not any significant difference...

Predicting suspended sediment load (SSL) in water resource management requires efficient and reliable predicted models. This study considers the support vector regression (SVR) method to predict daily load. Since SVR has unknown parameters, observer-teacher-learner-based Optimization (OTLBO) is integrated with model provide a novel hybrid predictive model. The combined genetic algorithm (SVR-GA...
