https://doi.org/10.22071/gsj.2017.78582.1047

Abstract
  The provenance of Jeirud Formation deposits (upper Devonian) in central Alborz has been investigated from study of siliciclastic sandstones (petrography, modal analysis and Heavy minerals assemblage) and mudstones (major and minor elements geochemistry). An integration of results suggest a mixture of ...  Read More
