South of Bazman volcano lies the broad Jaz Murian depression. To the south of this depression the Makran area separates the Arabian sea from inner Iran. The Makran area is geologically subdivided into the Inner Makran series which includes ophiolitic melange and the Coastal Makran Series. A phase of subduction commenced in the Cretaceous or Plio-Pleistocene, probably after earlier phases of subduction. This subduction has resulted in the formation of a volcanic complex including Bazman that stretches east-west and reaches a width of , and is known as the Makran-Chagai magmatic arc. There is also earthquake activity including the 1945 Makran earthquake, but overall earthquake activity in the Makran is low, probably due to the effect of sediments in the trench. A large accretionary prism formed directly behind the trench, in the trench the subduction occurs at a pace of . There is no evidence of a Wadati-Benioff zone beneath the Makran. Bazman has been grouped with Taftan volcano also in Iran and Koh-i-Sultan in Pakistan, of which only Taftan is considered active, Kuh-e-Nader is another volcanic field in this arc. This arc is over away from the trench, indicating that the subduction is very shallow. Within this arc, Bazman is located at the edge between the actual subduction and the continental collision zone. Bazman is also considered part of a long volcanic belt named the Urumieh-Dokhtar or Sahand-Bazman belt that extends from northwest to southeast and is accompanied by Cenozoic volcanic rocks and plutons. Bazman is sometimes considered to be part of a volcanic complex with the neighbouring Shahsavaran volcanic field.
