Surface temperature pattern analysis of Gach and Siah Tagh salt domes using remote sensing methods, Zagros area

Split-window algorithm is the effective method for determination of land surface temperature. The results of temperature pattern show that the Gach salt dome has a higher temperature than the Siah Tagh salt dome. From a structural point of veiw, the higher temperature of the Gach salt dome can be related to the rooting of this dome and its relationship with the basement salt column. While the lower temperature of the Siah Tagh salt dome can be due to the lack of connection between the salt dome and the salt source of Hormuz Series. Temperature anomaly maps show the different temperature pattern in these two salt domes. Spatial pattern of temperature anomaly in the Siah Tagh dome show the linear trend in the eastern part of the dome. This temperature linear pattern in the Siah Tagh dome probably is related to the morning sunshine in the eastern slope of this dome. According to the resulting LST map, the highest temperature in the Gach salt dome is 41.87 °C and 36.7 °C in the Siah Tagh salt dome.
