The Eocene-Oligocene Sarbisheh volcanic complex is a part of the Lut-Sistan Zone that outcrops in eastern Iran. In the east of this complex, three groups of volcanic rocks (i.e., andesite, dacite, and rhyolite) exist. Plagioclase as the main mineral of these rocks is found with varying micro-textures. Based on a changing trend in the concentration of anorthite, the developed micro-textures (coa...

the study area is located at northwest of sarbisheh in south khorasan province and eastern border of lut block. in this area, tertiary (eocene-oligocene to pliocene) volcanic rocks consisting of basaltic andesite, dacite, rhyodacite, vitreous rhyolite (perlitic in some parts), tuff and ignimbrite are exposed. in the daghar mountain, a, b and c perlite layers with thicknesses of 102, 7 and 58 me...

introduction the area reviewed and studied in this paper is located 5 km southeast of sarbisheh city at eastern border of the lut block (jung et al., 1983; karimpour et al., 2011; richards et al., 2012) in eastern iran between 59° 47′ and 59° 53′ e longitude and 32°30′ and 32°34′ n latitude. the magmatic activity in the lut block began in middle jurassic (165-162 ma) and reached its peak in ter...

TheM7.6 Nicoya earthquake struck at the interface between the Cocos plate and the Caribbean plate on 5 September 2012 inducing a ground acceleration of 0.5 m s−2 at the Irazú-Turrialba volcanic complex. We use data from six seismic stations deployed around and atop the Irazú-Turrialba volcanic complex to show the increase of local seismic activity after the M7.6 Nicoya earthquake. The response ...

BACKGROUND Cutaneous leishmaniasis due to Leishmania major is a serious and increasing problem affecting many rural areas of 17 out of 31 provinces in Iran. Little is known about sand fly fauna and leishmaniases in Eastern Iran and no study has been carried out in Sarbisheh County. The aim of this study was to determine sand flies composition and probable Leishmania infection to find the probab...

Volcanic eruptions are major natural disturbances with varied and complex consequences. Recent studies of how plants colonize newly created volcanic surfaces already have begun to clarify our understanding of succession. Because volcanoes create disturbance mosaics, it is imperative that we more fully understand the biotic responses. The 1883 eruption of Krakatau captured the world’s imaginatio...
