Title

INVESTIGATION OF SOURCE REGION PROPERTIES OF ALKALINE BASIC ROCKS IN THE BASE OF SHEMSHAK FORMATION IN THE EASTERN ALBORZ ZONE

Pages

  17-29

Abstract

 The ALKALINE BASIC ROCKS in the base of the SHEMSHAK Formation scattered mainly as intrusive and occasionally as extrusive, in some areas of the EASTERN ALBORZ zone. Their petrological compositions range from olivine gabbro to monzonite in intrusives and are olivine basalt in extrusives. Intracontinental settings of these rocks have been confirmed in various tectonomagmatic diagrams. Geochemical and petrogenetical investigations show that magma forming of these rocks, originated from 10-15 of percentages partial melting of an enriched subcontinental lithospheric mantle source with garnet-lherzolitic composition. This alkaline magma has been formed at 25-30 kbar pressures in 90-100 km depths and contaminated by continental rocks in small amounts, during rising and emplacement.
