Evidence has been provided of two mountain glaciations in the 4000 m-high, currently
non-glaciated Kuh- i -Jupar in the semiarid Zagros: an older period during the pre-LGM (Riss
glaciation, c. 130 Ka) and a younger one during the LGM (Würm glaciation, Isotop-stage 4-
2:60 -18 Ka). During the pre-LGM glaciation the glaciers reached a maximum of 17 km in
length; during the LGM glaciation they were 10-12 km long. They flowed down into the
mountain foreland as far as 2160, i.e. 1,900 m.
The thicknesses of the valley glaciers reached 550, i.e. 350 m. During the pre-LGM a 23 kmextended,
continuous piedmont glacier lobe has been developed parallel to the mountain foot.
During the LGM the glacier termini mainly remained isolated in the mountain foreland.
During the pre-LGM glaciation the ELA ran at 2,960 and during the LGM-glaciation at 3,060
m a.s.l, that is 1.590, i.e. 1,490 m below the current theoretical snow line. Thus, a temperature
depression of c. 11-16°C, i.e. 10-15°C is proved for the SE-Iranian highland, c. 130, ie. 60-18
