Qal'eh Hasan Ali is a maar-producing volcanic field located southeast of Kerman Province, Iran.

[5] This volcanic arc extends along the Zagros mountain range and has been interpreted as being caused by subduction of the Neotethys, starting during the Triassic.

[6] Another volcanic arc in Iran is found in the Makran area and is formed by the Bazman, Taftan and Koh-i-Sultan volcanoes, the second of which lies in Pakistan.

[5] Qal'eh Hasan Ali consists of maars,[5] and it covers a surface area of 150 square kilometres (58 sq mi).

[9] Qal'eh Hasan Ali is part of a large orogenic province that was formed by the closures of the Paleotethys, Neotethys and the Sistan oceans as well as by ongoing subduction off the Makran area.

[2] Qal'eh Hasan Ali lies on the Lut block,[15] over continental crust with a thickness exceeding 25 kilometres (16 mi).

[17] The formation of magma at Qal'eh Hasan Ali ultimately might depend on either the ongoing subduction at the Makran arc or to pre-existent asthenospheric processes.

[20] The tephrites contain analcime, anorthoclase, clinopyroxene, hauyne, magnetite, olivine, phlogopite and pyroxene dominated by augite and lesser aegirine.

[24] Qal'eh Hasan Ali has been active during the Quaternary,[5] the eruptions that formed the craters probably took place between 5,000 and 50,000 years ago.

In the case of Qal'eh Hasan Ali, the water may have been supplied by groundwater from the neighbouring Rud-e-Sang Zard river.
