Title

MAGMA MIXING EVIDENCES IN BASALTS OF ARDABIL AREA BASED ON PETRO GRAPHICAL STUDIES

Pages

  71-80

Abstract

 Ardabil region is part of the western Alborz-Azerbaijan zone in terms of structural classification. BASALTic lavas of this region have been studied in three areas: Heiran, Razei and Saein. The lavas in these areas are associated in age with upper Cretaceous to Quaternary. The outcrops of pillow lavas, prisms, dykes and lava flows in the different points are evidences for submarine and aerial volcanic activities in these areas. Microscopic studies of these rocks has shown the magmatic evolution especially MAGMA MIXING in these rocks. This phenomenon is observed in all of the three areas under study. With regard to petro graphical characteristic, the rocks under study range from andesitic BASALT to olivine BASALT. Accumulation of non equilibrated minerals, selective alteration of minerals, assimilation and opacity of mineral rims and serration edge of phenocrysts are MAGMA MIXING evidences in these samples. Also it is necessary to add variation in chemical composition and alternative zoning in clinopyroxene, inclusion zones in plagioclases, presence of two generations of plagioclases and needle apatite to these evidences.
