Pollination is the mechanical transfer of male pollen of a flower on the female stigma.This process has a fundamental role to survive the plants species.Since this process is invisible ,its importance has been ignored.Insufficient pollination can be harmful for the farmer instead of being useful.Pollination can be done via some ways.The most important ways are done by insects and wind.Pistachio...

Pichagchi pluton is situated in the northeastern part of the Soursat complex in Sanandaj-Sirjan metamorphic belt of Iran. The pluton with the age of 74.20 Ma is composed mainly granodiorite, diorite, and tonalite in which mafic minerals are biotite and amphibole. In this study, composition of minerals used to describe the nature of the granitic magma and estimate the pressure and temperature at...

introduction the area studied is located north of azna (lorestan province) in a small portion of the sanandaj – sirjan structural zone (mohajjel et al., 2003).this area is part of the zagros orogenic belt, formed by the opening and closure of neotethyan ocean. from ne to sw, it consists of three parallel tectonic regions: the orumieh-dokhtar magmatic belt, the sanandaj-sirjan structural zone an...

there are three different basic dykes in the northeast of golpayegan area, central part of sanandaj-sirjan zone (ssz) including: mylonitic gabbros (group 1), alkali dioritic-basanitic dykes (group 2) and alkali monzogabbroic to monzodioritic dykes (group 3). group 2 and 3 cut post-collisional rocks and are related to after subduction processes of neo-tethys. geochemistry characteristic of studi...

biotite samples from different units of boroujerd granitoid complex (bgc) of the sanandaj-sirjan zone, western iran, have beenanalyzed by electron microprobe for major elements. biotite analyses from three units of quartzdiorite, granodiorite and monzograniteof bgc have their own distinct non-overlapping compositional fields in the annite – siderophyllite – phlogopite – eastonitequadrilateral (...

deformation pattern of the northeastern part of the iranian-arabian collision zone (i.e., mainly sanandaj-sirjan belt or zone) is the main concern of this paper. here, we investigate the stress distribution and displacement pattern of eghlid-deh bid area as affected by the position of zagros suture using a three dimensional mechanical model. the modeled area is located between the zagros thrust...
