Misho granitoid pluton is exposed at the North Western part of the Misho Mountains and at the South Western part of the Marand compresional depression. The minerals in the rocks of this pluton include unhedral to sub – hedral quartz, K – feldspar both as microcline with tartan twinning and sub - hedral to unhedral orthoclase, two generations of biotite and zircon, subhedral to euhedral plagioc...
East misho granitoid intrusion body, a part of Alborz-Azarbaijan zone, is located about 60 Km north west of Tabriz, NW Iran. This pluton with an area of about 50 km2 has cut percamberian unmetamorpic sedimentary rocks and, is covered with Permian sedimentary rocks with igneous nonconformity. Litological composition of the studied pluton displays a range of alkali granite, monzogranite and syeno...
Granitoidic bodies of the eastern Misho mountains (SW Marand – East Azerbaidjan) have intruded into Kahar Formation and mafic – ultramafic rocks of Misho mountains and has faulty contact with Triassic carbonate deposits. The composition of these bodies ranges from quartz monzonite to granite and alkali-granite and it is cut by porphyritic granitic and diabasic dykes. The main minerals of these ...
introduction there are some theories about the paleotethys event during the paleozoic that have been proposed by geologists (metcalfe, 2006). some scientist offered some pieces of evidence about the northern margin of gondwana (zhu et al., 2010). the paleotethys ocean and hercynian orogenic report first in iran, have been offered from the morrow and misho mountain (eftekharnejad, 1981). misho m...
misho intrusions outcrop in the southern part of north tabriz fault, east misho mountains, nw tabriz. filed studies, petrological and geochemical data show that both mafic and felsic rock types occur in the area. mafic rocks include gabbro consisting of plagioclase, clinopyroxene, olivine and opaque minerals and felsic bodies consist of alkali granite with k-feldspar, quartz, plagioclase and a ...
Data related to radioactivity released from the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident on 15 March 2011 gathered by residents of Miharu, Fukushima Prefecture, and by Tohoku University are presented. These data sets consist of (1) the earliest radiation monitoring by a Geiger counter in the town, (2) ratios of radioactivity between (132)Te and (137)Cs for a wide area between Fuku...
An alkaline volcanic activity with a relative Plio-Quaternary age (based on the succession of layers field) occurred in northern part Uromieh Dokhatar magmatic belt, Iran. Hornblendite xenoliths mostly displaying cumulitic texture occur trachyandesites from this episode. The thermobarometric results indicate that these formed within crust. Based mineralogical and chemical characteristics, are d...
introduction iran forms a relatively compact zone of active continental deformation resulted from the northward collision of arabia with eurasia during late cenozoic times, which is continuing to the present-day at a rate of 25 mm/yrs (from gps data). evidences of active tectonic in different parts of iran, has been studied and identified. the arid climate, low rates of erosion, and minimal veg...
extended abstractthunderstorm rainfall is one of the most important climatic phenomena in the northwest of iran that has specific variability in spatial distribution. these rains have an important role in case study area climates. the purpose of this study is investigation of spatial distribution of thunderstorm rainfall of mountainous areas of the northwest of iran to modeling thunderstorm in ...
