Title

PETROGENESIS AND PETROGRAPHY OF IGNEOUS ROCKS IN SOUTH - EAST OF BARN (JEBAL-E-BAREZ)

Pages

  4049-4066

Abstract

 The studied area is located in south-eastern Iran with a measurement about 510 Km2. The Igneous nicks of this area belong to teriary. The oldest part is eocene volcanic and pyroclastic rocks, as andesite-basalt, andesite, lathite andesite, dactie, acidic to intermediate tuffs and ignimbrite. A batholitic body intruded in the volcanic rocks in miocene. This batholite is composed of diorite and granithoidic (tonalite, granodiorite porphyry" granodiorite porphyry granitc porphyry and granophyre) rocks. According to field observation, geochemical and tectonomagmatic studies, there are two different magmatic episode as volcanism and plutonium. In this area differentiation of calk - alkline pyroxene and plagioclase is the main reason of evolution for the calcalkine volcanic rocks. There was a dioritic magma in the miocene which a small part of it intruded in the volcanic rocks directly. The differentiation of pyroxene, plagioclasc and titonomagnetite minerals changed the composition of the magma. Then different granitoidic rocks were formed in respect to composition and the depth of magma. The granitioidic rocks are I type and belong to (VAG) group. According to their spider diagrams they are very similar to Lima granite in Peru, which is a continental margine granite.
