ABSTRACT: The salt domes of the west
Zanjan (Central Iran) are the most important structures in the study area. They
have been formed by the uplifting and erosion together under low humidity and
dry and warm climate condition. The salt rocks with near to 200 meters thickness
are related to lower member of the Upper Red Formation (Early Miocene) that
deposited in the inverted back arc basin. They have been formed in the Central
Iran basin after the Arabian-Eurasian convergence. Based on filed works and
preparation of geologic map, salt domes have been cropped out during regional
uplifting and erosion along hinge zone of a longitudinal anticline. Also, there
is no evidence for salt diapirism and so, they are different from some salt
diapirs in the southwestern margin of Zanjan that is investigated by other
researchers.
