Abstract
  The pillow basalts, Cretaceous in age, outcrop in the northern part of Alborz in the East of Guilan province (north of Iran). The pillow lavas are mainly olivine basalts. From geochemical point of view, these rocks are transitional or mildly alkalic series and negative anomaly of Nb-Ta, Zr, Ba; positive ...  Read More

Abstract
       Petrological,geochemical and isotropic evidence of crustal contamination of the Quaternary basic rocks of Ghorveh-Takab axis is presented in this paper. These rocks are olivine basalt and basalt and they are plotted in the field of alkaline suites in geochemical diagrams. Some ...  Read More
