Abstract :

After the age of Euosen, the plain of Ardabil has been appeared like a subsidence hole, by faults (Neuor, Hir, Anbaran …) and the sediments wich are sensitive to Quaternaring erison have covered them. also From beginning of the middle age of Oligocene mountains of the reigion have been elevated and the next age of erosion has started. the orogency of Pasadenian causes faulting mild thrust and region elevation. The existence of congolomerate with fragile cement and volcanic pieces in the southen part of Ardabil in Peleo- Quaternary are the sings  of  havy rain fall in the beginning of Quaternary. The new alluvium of Quaternary(Holocene) have been  carried through by mountaion waterway to the Ardabil plain and his process is done by the region water ways at the present time. The Alluvial terraces, alluvial con and … are signs of instability of the western slops of Talesh mountains and its morphological effects on filled plain of Ardabil.
