A 500-m-wide crater caps the summit of the dominantly andesitic-dacitic volcano, the flanks of which are covered by monogenetic centres especially to the northwest.

[10] These mountain chains surround Central Iran, in whose southern part lies the Lut block and Bazman.

Tectonically, southern central Iran does not follow the typical Alpide geological patterns insofar as faults are rare and the folds in the crust are broad.

On the north flank, a northbound lava flow with prominent levees that eventually splits into a northwestern and northeastern arm was discharged by a steep lava cone[29][1] that is known as Bazman Bacheh ("Bazman's Child") and lies 3 kilometres (1.9 mi) northeast of the summit.

[30] Other viscous lava flows have been erupted from satellite cones,[29] which occur mainly at distances of 10–20 kilometres (6.2–12.4 mi) northeast from the summit.

The varying state of erosion of these volcanoes indicates they formed over many millennia; some have been worn down to their feeding dykes.

[12] Bazman has no recorded historical eruptions but fumarolic activity has been reported,[1] as well as ongoing surface deformation.

[4] Hot springs containing iron and sulfur are other signs of ongoing volcanism;[35] Bazman has been considered a potential site for development of geothermal energy, with a surface area of 8,356 square kilometres (3,226 sq mi).

[46] Towns and in particular roads around the volcano could be threatened by lava flows, ash falls and nuee ardente emission, in case of renewed eruptions.

Most of this detritus is erosional in nature, but pyroclastic rocks created by explosive activity and hot avalanches of extruded lava also contribute.

[12] 120 metres (390 ft) thick olivine basalt found in the Jaz Murian depression may also come from Bazman.

[39] Petrological analysis at the monogenetic volcanoes around Bazman has indicated porphyritic basalts containing clinopyroxene, hornblende, olivine and plagioclase, and titanite and zircon as accessories.

[23] On the basis of its composition, the environmental conditions under which one of the samples formed have been estimated, the temperature being c. 1,400 °C (2,550 °F) and a minimum depth of about 76 kilometres (47 mi).

[56] A mining area is associated with Bazman and more precisely with Paleozoic-Mesozoic rocks including a c. 70 million years old granite pluton.

[44] Various hydrothermal and skarn alterations have generated mineral deposits that include silver, gold, copper, lead, magnesium, molybdenum, and zinc, and minor amounts of tungsten and possibly of vanadium.

Together with other kinds of erosion such as frost and salt weathering, these have formed a pediplain terrain with inselbergs being left, especially where harder rocks are found.

[60] The effects of this erosion have mantled the volcano with debris locally known as "dasht", reaching distances of over 30 kilometres (19 mi) from the vent.

[3] The 3,246.88 square kilometres (1,253.63 sq mi) Bazman protected area encompasses part of the volcano.

[61] Animal species recorded there include the Asian black bear, bustard, chinkara and sand cat.
