The productive mineralization of the Sheikhdzheili-Zengiboba area is associated with metamorphogenic transformations rocks Urusai, Karauzyak, Kuyanchik, Sheikhdzheili suites, metamorphosed under conditions green schist facies. mineralized zones site are confined to narrow faults in tectonic northeast and northwest directions. main form manifestation gold-bearing small steeply dipping veins, len...

to modeling of suitability iranian oak site to establish coppice regenerations, chahartagh forest reserve, ardal region, chaharmehal and bakhtiari province, southern zagros forest, and southwest iranian state was selected. to modeling suitability iranian oak used the physiographic element, soil depth, climatology and distance from village selected. to this study used the raster formats by pixel...

[1] We use the GEOS-Chem chemical transport model to interpret observations of tropospheric ozone from the Tropospheric Emission Spectrometer (TES) satellite instrument in summer 2005. Observations from TES reveal elevated ozone in the middle troposphere (500–400 hPa) across North Africa and the Middle East. Observed ozone abundances in the middle troposphere are at a maximum in summer and a mi...

western and eastern populations of goitered gazelles are separated by zagors mountains as a barrier. bordering iraq, western population has suffered from drastic decline during and after iran-iraq war. presently, there are small numbers of the goitered gazelles left in the region with no clear understanding of their taxonomic status. it has been normally assumed that there should be a differenc...

The Relationship between wildfire areas and physiographic features in the Zagros vegetation area, Kermanshah province

Climate plays a key role in ecosystem services. Understanding microclimate change can be significant help making the right decision for ecosystems and buffering effects of global warming. Given large distances between meteorological stations changes climate variables within short distances, such variations cannot detected just by using observed data. This study aimed at determining spatial stru...

the life table parameters of schizaphis graminum (rondani) (hemiptera: aphididae) on four commercial cultivars of wheat (kohdasht, pastor, tajan and zagros) were determined in laboratory conditions. fertility life table were constructed using age-specific survivorship (lx) and age-specific fecundity (mx) and subsequently analyzed using jackknife method and anova. there were significant differen...

Abstract On 15 May 2020 an Mww 6.5 earthquake occurred beneath the Monte Cristo Range in Mina Deflection region of western Nevada. Rapid deployment eight temporary seismic stations enabled detailed analysis its productive and slowly decaying aftershock sequence (p=0.8), which included ?18,000 autodetected events 3.5 months. Double-difference, waveform-based relative relocation 16,714 earthquake...

faults/fractures detection is an essential step of the full field study in hydrocarbon reservoir. definition of exact location of these structural events is a critical step to optimize location of the development wells. despite of the fast development of the geo science technology and oil industry in recent years, detection of the small geological events such as faults and fractures in some of ...
