With an elevation of 4055 metres,
shir kuh or Shirkuh (Persian: شیرکوه) is a high peak in the central part of
Iran about 40 kilometres southwest of the city of
yazd in
yazd Province.
Geologically,
shir kuh is made chiefly of Jurassic granite surrounded by Cretaceous rocks. It is located almost in the vicinity of the Sahand-Bazman volcanic arc, a volcanic arc that was formed during the Tertiary and mainly in the Eocene volcanism.
shir kuh consists mainly of intrusive rocks (Jurassic granite) that were made in the Late Cimmerian orogeny in the Late Jurassic.
This mountain is located in the
Sanandaj-
Sirjan geological and structural zone.
Sanandaj-
Sirjan was subjected to magmatism and metamorphism in the Paleozoic and Mesozoic. This section along with other Iranian microplates were separated from Gondwana in the Carboniferous (when
...see more magmatism was caused by rifting and the process of detachment) and moved northwards.
From the Early Jurassic to the Middle Miocene Sanandaj-Sirjan was adjacent to a subduction zone and there was magmatism because of the subduction zone which was situated in the south and southwest of this structural zone.
Consequently, in the Late Jurassic, Sanandaj-Sirjan region was subjected to the magmatism of the Late Cimmerian orogeny in the form of both volcanism and plutonism.
shir kuh was formed as a result of the plutonism of this orogenic phase.
Having a high elevation, shir kuh and its neighbourhood have a cold mountain climate although the region is placed in a location that is surrounded by a hot semi-desert climate.
