Some aspects of Shekarnab intrusion petrology, NEQazvin, Iran

Category Petrology
Group GSI.IR
Location 21th symposium on geosciences
Holding Date 21 May 2008

Abstract:
      Shekarnab magmatic intrusion, which is located in the NE of Qazvin, has intruded into the Paleogene volcanic rocks of central Alborz. The intrusive rocks are generally consisted of different parts including monzonite, gabbro and syenite. These rocks, geochemically, show alkaline and metaluminus characteristics. Both the REE pattern and the negative anomalies of Nb, Hf and Ti of the rocks resemble to those of the subduction zones granitoids rocks.
