چکیده مقاله:
The coastal region of Chabahar Gulf with 1113.7km2 area has been located in the southeast of Iran. In this research, satellite images of ETM+ (2004) were used in order to zoning of sedimentary environments in this Gulf. Methodology of this research was baesd on synthesis of supervised and unsupervisedclassifications in GIS and ENVI softwares. Based on studies and calculation of OIF index, the best selected bands to differentiation of sedimentary environments are 1, 5 and 7 bands of ETM+ that had most information. Zoning maps indicate that in the study area, wide bodies of sedimentary environmentsconsist of profound marine environment (41.13%), Shallow marine environment (7.9%), Sabkha and saltflats (3.07%), Intertidal and lagoon (1.2%), Delta (1.33), Siliciclastic barrier and Aeolian dune (6.45%), Loose Sandy sediments (11.98%), Mud flats (26.93%).
