Abstarct: Kuhe-Cheft sub-volcanic intrusion is part of the Turoud – Chah-Shirin magmatic belt and located in the northern part of Central Iranian structural zone. Volcanic-pyroclastic sequences of Eocene including of volcanic breccia,,agglomerate and red-purple tuff are the host rocks. The studied elliptical - shaped and sub-volcanic intrusion is hornblende porphyritic diorite in composition and calc-alkaline, and cut volcanic-pyroclastic sequences. Plagioclase is the main constituent mineral, hornblende and small amount of biotite, magnetite, apatite and quartz are the most important accessory minerals. Different types of alterations including of phyllic and less chloritic are observed at some samples. In order to investigation of the emplacement mechanism of this sub-volcanic intrusion, anisotropy of magnetic susceptibility (AMS) is used. Since the bulk magnetic susceptibility (Km) of all samples is higher than 500 μSI, the intrusion belongs to ferromagnetic and magnetite series granites. The highest degree of anisotropy (P%) observes along the small diameter of Kuhe-Cheft elliptical intrusion. The lowest anisotropy occurs along the large diameter i.e., the northern east to west - southwest of the intrusion. Despite the relatively high strain, no microstructure is recorded due to porphyry nature and high proportion of liquid/crystal at the time of emplacement. Highest areas and around the roof of Kuhe-Cheft intrusion, shaped parameter (T) is oblate and positive. Some stations at the south-western part of dioritic intrusion have high-plunge magnetic lineations and prolate shape parameters. This part can consider as feeder zone. At other part of intrusion, lineation is low to medium plunges. Strike of foliation at the sampling stations display concentric pattern and the slopes are above 30 degrees.The absence of petrographic zonation, concentric pattern through the sub-volcanic intrusion from core to contact with country rocks, oblate fabric at the floor of intrusion, intense crushing and deformation at the country rocks especially at western margins are the main evidences that the pluton emplaced as a balloon. According to the left-slip faults of Anjilo and Toroud and govern tectonics of the region during the emplacement of the studied intrusion, it can be concluded that a dextral shear zone providing tensional spaces required for magma ascend and emplacement at Torud-chahshirin magmatic belt.
