Title

PETROGENETIC STUDY OF QUATERNARY BASALTIC ROCKS FROM AZERBAIJAN, NW IRAN

Pages

  37-50

Abstract

 The study area is located in northwest of Iran, in the western Alborz-Azerbaijan structural zone.Based on petrography and geochemical studies, the Quaternary basic volcanic rocks of the study area have alkali-olivine BASALT and trachy BASALT composition and alkaline-subalkaline nature. According to tectonic diagrams, the samples are plotted within-plate continental BASALTs field. The Quaternary volcanic centers are situated within pull-apart basin structures and are controlled by active faults. The average Ce/Pb and Nb/U ratios of the studied BASALTs are lower than the value, for average oceanic BASALTs (OIB and MORB).These ratios are close to the average values of sub-continental LITHOSPHERIC MANTLE. According to geochemical characteristics of trace elements and REE patterns, all the analyzed BASALT samples have LREE enrichment chondrite-normalized REE patterns, suggesting that they may have been generated by different partial melting degrees (Ahar 3-4%, Maku 10-15% and Sarab 5-15%) of a sub-continemtal LITHOSPHERIC MANTLE source.
