Abstract: 

There are about 200 salt doms in the south of Zagros mountain and Persian Gulf. In some areas of these salty doms, there are karsty sinkholes which cause special features in natural structures and morphology and influence the quality of surface water and ground water .The aim of this research is to study the morphology of Jahani salt mountain with the use of lab methods and field observation, aerial pictures, safelights images topography and making go logical map with the scale 1: 50000.
The sinkholes are the main karst Phenomena's in the salty domes.
The distribution of the sinkholes are studied via Arial pictures 1:20000, 1:40000 and field studies. (field researches).
The sinkholes have different forms most of which have forms like funnel shaped and bowl shaped or circular with single or several holes they change according to slope, height, size and number and they are in most areas dispersed. It seems that tectonically forces haven` t had in fluency or have had little influence on their existence.
(Faults have caused the existence of tectonically sinkholes. The sinkholes exist around the faults).The mineral and salt water springs inside and around these salt domes are other karst phenomena' s.
Main karst forms in the area are rillen Karen, slide, salty openings which exist as the result of tectonically forces and solution, caves, salty thin vallies, solution galleries and solution columns called genie chimney.
