 Iranís volcanoes 
Mount Bazman
Bazman is the youngest volcano of Iran.  This
semi-active volcano is 115km away from northwest of
Iranshahr and 120km away from western Khash.  Its
height from sea level is 3490m.  Bazmanís cone is
stratovolcano type.  It is made of pumice, lava and
breccia, alternately.  This volcano appeared during
Quaternary.  Around main peaks, a couple of small
cones made of basalt lavas are observable.  Known
rocks made of acidic lavas are seen in eastern flanks
which are; andesite and dacite.  Diameter of the
biggest crater is about 5000m.
Existence of hot springs and emitted gases cause
changement in color of rocks and available tuffs in
the peaks may introduce a semi-active volcano.      
     
Mount Damavand
Damavand is the highest peak of the Alborz having a
height of 5670m from sea level located in northern
Tehran.  Damavand volcano is Stromboli type holding a
layered cone.  Its crater has a diameter of 400m.  The
central part of its crater has a frozen lake.  The
peak of this mount was built 100,000 years ago
(Holocene).  Its last activity has been in late
Quaternary.  The existence of sulfuric and hot water
springs, such as Haraz hot water springs, Ab-e-ask,
etc indicating the Earthís internal heat in this
region.  Mount Damavand is a semi-active volcano,
indeed.
This volcano has produced a lot of pumice, tuff,
sediment and lahar.  In the western foothill of this
mountain, the beautiful natural lake of Lar is
available.  This lake appeared when lavas coming out
of Mount Damavand closed the Lar River route.
 
Mount Sabalan
This mountain is a point type volcano bearing
stratovolcano cone.  Its height is 4800m from sea
level located in the western part of Ardebil.  This
mount includes three cones along with each other. 
Lava vast distribution (area of about 1300sq.km)
indicates huge explosion and discharge of lava high
volume.  
Sabalan region is located on the Oligocene big horst,
geologically.  Its activity commenced from Eocene. At
present, the only sign of Mount Sabalan activity is
various sulfuric and hot water springs indicating
post-volcanism phenomenon.  At the base of the highest
peak of Sabalan, a small lake exits.
 
Mount Sahand
It includes 12 cones separated from each other for a
couple of kilometers.  Sahandís height is 3600m and
located in southeastern of Tabriz.  Its vast cone is
made of tuff and ash.  Existence of high volume of ash
and pumice pieces in far distances indicates vigorous
explosion of this mount.  This phenomenon has probably
had an effect on the burial of mammals of around
Maraqeh (Darvishzadeh).  The compostion Sahand lava
has been rhyolitic, dacitic and andestic.  The
activity of this volcano has been started from early
Quaternary, and today it is in relative calmness
period.
 
Mount Taftan
Mount Taftan is a semi-active volcano and
stratovolcano type having a height of 4050m from sea
level and is the highest mount of Baluchestan located
near Khash City.  Taftan lavas are andesitic.  Various
sulfuric springs surrounding this mount and gas
emission from its highest peak introduce the view of
an active volcano.  It has been reported that molten
materials came out from Taftan within 1970 and 1971
