Location 21th symposium on geosciences
Holding Date 21 May 2008

Abstract:
      The Cheshmeh Sefid intrusive body has intruded the regional metamorphic rocks which are belongs to Precambrian. In parts of this huge body there is some pegmatite.
   The following mineral assemblage are distinguished ;alkali feldspar (microcline , pertite , ortoclase , albite ) plagioclase , pyroxene , hornblende , magnetite, apatite , pyrite , allanite , calsite , zircon , biotite . The geochemical data has revealed that Ti ? rich magma with transitional nature is responsible for this magmatism.

   General:
     The Cheshmeh Sefid intrusive body has intruded the regional metamorphic rocks which are belongs to Precambrian. In parts of this huge body there is some pegmatite.
   The following mineral assemblage are distinguished; alkali feldspar (microcline, pertite, ortoclase, albite) plagioclase, pytoxene, hornblende, magnetite, apatite, pyrite, allanite, calsite, zircon, biotite.
   The geochemical data has revealed that Ti-rich magma with transitional nature is responsible for this magmatism.
