Abstract :

The basaltic rocks of this case study are located in NE of Darood – Neyshaboor in NE of Iran between 59 8 to 59 16 east longitude and 36 7 to 36 11 north latitude. The age of these rocks is Silurian and based on naming diagram, the rocks of this studied area are alkali basalt. Different diagrams show the origin of magma which produced sodik alkaline and changed unadoptable elements such as LILE (Ba, Rb, K, Th) which are accepted the intense ffect of alteration in their rocks and HIFSE elements (Na, Ti, Ta) are riched which show the ource of riche mantle for these rocks, also pb positive anomalies in spider diagrams show he articipation of crustal elements in the rocks petrogenes of his region. Tectonical setting of these rocks confirms that these basalts of studied area are intra plate.
