(a) Landsat image (RGB 531) of the main dome and spreading namakiers at Syahoo. The position of the topographic profiles (A–D) across the dome and surrounding namakiers are shown. (b) Exaggerated topographic profiles (A–D) across Syahoo, with vertical and horizontal scales in km. The profiles represent the level of the salt surface, apart from at the country rock buttress in D–D'. The pronounced shape of the central dome surrounded by a relatively flat salt apron should be noted.

(a) View looking north at Syahoo using a 3D spot image with a resolution of 5 m and 1.5× vertical exaggeration. It should be noted how the (darker) salt flows around the edge of the east–west-trending country rock buttress. (b) Vertically exaggerated (3×) Google Earth image looking towards the NE and highlighting the topography of the central dome and surrounding salt apron. The east–west-trending country rock buttress deflects the southern flowing namakier around the eastern end of the salt dam. (c) Field photograph looking east towards the western flank of Syahoo showing faintly banded salt with a orange–brown-weathering crust overlying recent gravels (photograph by P. Soodoshoar, 2007).

Simplified summary maps based on the 12 InSAR increments of the Syahoo study shown in Figure 5. Increments 1–12 are represented by (a)–(l) respectively, and highlight uplift (+) with warm (red) colours and subsidence (−) with cool (blue) colours. Arrows schematically indicate inferred direction of surficial salt flow, assuming salt flows down-slope out of subsiding (deflating) areas and into uplifted (inflated) areas. The central dome is shown by the dotted line. (Refer to Fig. 5 and Table 2 for further description.)

(a) Perspective view towards the north of Syahoo showing the location of nine points chosen for InSAR analysis. (b) InSAR analysis of five points on the main dome and (c) four points on the surrounding namakiers for consecutive increments 5–12 (from 7 August 2003 to 18 May 2006). The displacement of the salt surface along the line of sight (Los) is plotted (in metres) against time (in days) for these increments. The plots suggest that the markers in the main dome and namakiers broadly display uplift, although areas of local subsidence are also recorded.

Cumulative InSAR map (a) and synoptic summary map (b) of Syahoo combining all uplift (positive and shown in reds) and subsidence (negative and shown in dark blue) in increments 5–12 (1015 continuous days from 7 August 2003 to 18 May 2006). Arrows schematically indicate inferred direction of surficial salt flow, assuming salt flows down-slope out of subsiding (deflating) areas and into uplifted (inflated) areas. The maps show that the central dome (dotted line) and most of the adjacent salt sheet underwent uplift during this period.

Salt extrusion kinematics: insights from existing data, morphology and InSAR modelling of the active emergent Anguru diapir in the Zagros fold and thrust belt, Iran Available to Purchase

We used interferometric synthetic aperture radar (InSAR) time-series data to evaluate surface displacement over the salt dome by constructing 236...
