Classification and Quantitative Characteristics Analysis of Iran North- West Salt Domes from Aspect of Structure

There are more than 50 salt domes with neogene age in the northwest of Iran 48 Domes of which have measurable dimensions. One of the criteria's according with which we can classify Iran north-west salt domes is structural features of salt's appearances in the region.
In this article salt domes in north west of Iran, according to their structural characteristics, have been divided into two groups with mono-clinal structure and anticline structure, at first the scatter diagram, regression line, the kind and amount of correlation between morphometric parameters of each group have been analyzed. Then the parameters of each group have been compared with those of the other group.
Examining the salt domes morphometric parameters show that mono-clinal domes in comparison with the anticlinal domes have area, circularity coefficient and height but more stretching and elongation coefficient. Also, mono-clinal domes are located on faults or in a near distance from faults, therefore the mono-clinal domes in comparison with the anticlinal domes, are more influenced by the faults
