Abstract: 

In spite of the earlier extensive petrological studies on the Alvand plutonic body, the study of geological structures of this body, had been less considered. Geological structures of this plutonic complex is various and investigable as same as it's petrological variety. Some of the most important primary (magmatic) and secondary (tectonic) structures of granites of this plutonic complex are:
I) primary structures, including of orientation of phenocrysts of feldspar, mica, enclaves and primary fractures or joints, which comprise essential part of the discussion of this paper. This structures confirm an internal flow and syn-emplacement fractures inside the intrusive body.
2) Tectonic structures, including of tectonic fractures and structural changes in rock bodies in solid - state after solidification of plutonic body.
The study of primary and secondary strutures of the Alvand granites show that, the structures of this plutonic body can be an important pattern for studying granite tectonic models and many relationships between internal and external (environmental) structures of the intrusive bodies.
