Study of Mahmoodabad Intrusive mass (SW of Takab)

Category Petrology
Group GSI.IR
Location 21th symposium on geosciences
Holding Date 21 May 2008

   Abstract:
      The studied area is located in the east of Takab (eastsouth of Dandi) in centeral Iran structural zone. In this area, metamorphic, Igneous and sedimentary rocks have outcropped whose stratums generally consist of Oligomiocene sediments. Most of faults in this area are thrust with direction eastsouth ? westnorth strike.
   A mass of granitoid of Mahmood-Abad is the most important igneous intrusive mass which outcropped between metamorphic rocks (metabasites). Some parts of this granite turned into cataclastic granite under the function of shear forces. The compound of this granite is granite or monzogranite.
   It has idimorph garnet crystal and xenoliths from metamorphic rock in Mahmood?abad granitoid mass. This granite is peraluminous and calc-alkaline granite and was probably made in a continental collision environment (CCG).This granite shows the greatest symmetry with S? Type granites according to the studies.
