Abstract :
Kabudan area located in NE Iran at north of small city Bardaskan. The study area belongs to central Iran tectono- volcano- sedimentary zone (Taknar sub-zone) and centeral Domain of Alp- Himalaya belt. Taknar sub-zone restricted by Sabzevar Ophiolite belt at north and Daruneh Fault at south. Taknar sub-zones separated from Sabzevar sub-zones at north by Rivash or Taknar fault. Sabzevar Ophiolite is a part of Neotethys remants (Mesozoic) in Iran, Whereas the Taknar Formation or Zone is a imperfect intercontinent rift that has been attributed to Precambrian in age. In addition to Taknar famous copper mine at western part, during oure field work, has been identified as new massive sulfide deposits in the Kabudan area( Eastren part of Taknar Zone). In view of Economical geology, mineralization in this area distinguished as "Syngenetic" and "Epygenetic" Types. It seems that the syngenetic Type is related to submarine and Acidic volcanism. Late plotonic and/or syn-volcanic processes have intensified mineralization and alteration in this area. In the Taknar zone, mineralization related to" Resurgence Calderaes" and Berrecciated – Rhyolitic doms that has been contained Q-Fel rocks. This mineralization related to enrichment magnetite deposits of Koroku VMS Type. Mineralization in this area; includes of Au, Zn, Ag, Fe, Pb, and Cu, as well as As, Hg, Bi, Sb as accessory minerals. Au amounts in the Taknar Zone vary between 0.6 - 8 ppm. we recognized at least 13 target mines in the Kabudan sheet (in scale of 1:2500), that most of them (10) are in the Taknar Zone.
