Title

VEIN-TYPE AND STRATABOUND W (CU-AU) MINERALIZATION IN IRAN

Pages

  305-314

Abstract

 Tungsten (Cu-Au-Zn) deposits and occurrences in IRAN can be divided into two separate categories based on their genesis, tectonic setting, mineral par agenesis and related processes inherent in their formation. The first category contains deposits, which are located in metamorphosed Late Triassic-Middle Jurassic volcano-sedimentary sequences, and their distribution is indicated by layering. These deposits are located in a specific stratigraphic position and are concentrated in contact of volcanic units with carbonate rocks. The geodynamic setting of this category probably is INTRACONTINENTAL RIFTing. The second category contains deposits located in metamorphosed sedimentary rocks of the Shemshak group and JURASSIC GRANITOIDS. These deposits have vein-veinlet geometry and their formation is controlled by faults, fractures and shear zones. The geodynamic setting of this category probably is ACTIVE CONTINENTAL MARGINs. The mineral paragenesis of the first group generally contains scheelite and Cu-Fe-Zn sulfides, whereas the paragenesis of the second group is wolframite, scheelite, chalcopyrite, arsenopyrite, with gold and specifically bismuth.
