Abstract Preciously, many geologists have tried to interpret different aspects of Zagros salt diapirs. In this research, the quantitative characteristics such as their size and shape of salt diapirs in eastern Zagros are determined using digital elevation models (DEMs). This could represent an essential step in figuring out what influences their morphology and growth. Also, focusing on the surface morphology of those helps in better understanding the formation and emplacement mechanisms and potentially their related deposits, such as salt and iron. This is accomplished through accessible published data, such as DEMs and geological maps, as well as field studies on where salt flows out of diapirs, with a particular emphasis on the diapirs that we consider representative. The studied area is located at the eastern tip of the Zagros system close to the Makran accretionary prism and Persian Gulf, which is pierced by 21 salt diapirs. Geologically, these diapirs are mainly surrounded by the Tertiary Asmari‐Jahrum, Razak, Mishan, Aghajari, Bakhtyari, and Guri Member Formations, as well as the Quaternary sediments. By processing DEM data and geological mapping, the boundary of the salt dome was determined to calculate some size parameters. After that, we delimited two independent shape descriptor indexes, the irregularity index and the ellipticity index, which effectively characterize the shape of salt diapirs. Smaller diapirs exhibit lower values of both ellipticity and irregularity. Furthermore, the ellipticity and irregularity values of the diapirs near the Persian Gulf coast, such as Hormuz and Gachin, are lower. Diapirs of Ahmadi, Moran, Darbast, Khain, and Khush‐Kuh exhibit irregular and linear shapes. The appearance of this kind of salt diapir with high ellipticity and irregularity values is primarily associated with thrust or strike‐slip faults. In more active salt domes, with a higher rate of salt uprise, the size of the salt sheets is larger, which caused the exposure and spread of salt over a wide area. When salt emerges from a diapir above sea level, it gravitationally flows downward in the direction of the steepest slope. The most important factor in determining the morphometric characteristics of the studied salt structures is their tectonic position, which affects the emplacement mechanism, the rate of salt rising and regional uplift, as well as the rate of erosion, dissolution, and accumulation of sediments.
