Abstract :

Ophiolitic melange of south Birjand in east of Iran, composed of serpentinized peridotite, gabbro,
spilitic basalt and radiolarite. Occurence of compressional regime in Cretaceous and activation of strike slip and thrust faults in southeast of birjand, sheared mentioned rock unites. Distibution of magnesite deposites in this area consistent with serpentinized peridotite suits. Deformation style in southeast of Bagheran mountain controlled by N-S and E-W striking active fault
systems. Interaction of N-S striking right lateral faults and E-W striking left lateral faults, created a compressional area in south east of Bagheran mountain in south of birjand. Many thrust sheets are recognition in this part and limited by N-S and E-W striking faults.
Magnesite deposites suchas: Howz sefid, Chahkandook, Kalate abdollah, Razgh ,Minakhan,spigi,
Nowkaj,Holudar,Kuch. are concentrated in this part of mountaine. Because of tectonic characteristics and activation of thrust faults we expect to have more potential of magnesite mineralization in this part of mountain that situated in thrust sheets.
