Folding is a common mode of deformation in geology when mechanically layered rocks are subjected to compression. They occur on a wide range of scales from mm-scale to 10’s of kilometers in places where upper crustal rocks are compressed as a result of tectonic plate convergence (such as in the Zagros mountains, Iran). The physical instability that results in the formation of folds has been stud...

OBJECTIVES From the ancient era, emergence of Agriculture in the connecting region of Mesopotamia and the Iranian plateau at the foothills of the Zagros Mountains, made Iranian gene pool as an important source of populating the region. It has differentiated the population spread and different language groups. In order to trace the maternal genetic affinity between Iranians and other populations...

In recent years, in addition to pollution from cars, factories and other polluting devices, the country of Iran has been destination dust that have entered Iraq Saudi Arabia caused climate. this research, wettability some native plants Zagros Mountains investigated experimentally by measuring contact angle. Sampling oak trees Quercus brantii Lindl. species was carried out around Khorramabad cit...

Tree decline due to climate change results in physiological weaknesses, attacks by harmful pests and pathogens threats forest ecosystem stability. In the work described here, effects of drought on wood density, tree ring width variations vessel morphology are investigated Persian oak (Quercus brantii) Zagros Mountains, Ilam Province, western Iran. Discs cut from trunks declined healthy trees wo...
