In recent years, salt diapirs have been widely used for gas storing, hazardous waste disposal, mining, and petroleum production. The rate and pattern of active movement in salt structures are crucial to be obtained before planning these industrial utilizations. The central basin of the Iranian plateau represents well-exposed and -preserved diapirs that can be considered as an analog for other salt basins around the world where the exposures are not as good. Integration of the Interferometric Synthetic Aperture Radar (InSAR) technique with remote-sensing structural mapping permits us to study the active surficial deformation of eight salt diapirs in the Kalut basin in central Iran. We classify the Kalut diapiric structures into salt walls, massifs, stocks, and welds. We then use 75 Single Look Complex (SLC) IW scenes acquired on the ascending collected from November 2014 to November 2018 and 62 SLC images on descending geometries collected from October 2014 to January 2018, both covering the same period. The Sentinel-1 images are processed by the Small BAseline Subset (SBAS) approaches to define vertical and horizontal displacement maps revealing that the Kalut basin is one of the most-active present-day diapiric systems in the world, its eight salt diapirs are rising, and none of them subsides. Maximum calculated rates of growth reach 8 mm/yr in vertical and ~ 2 mm/yr in horizontal directions, suggesting that in general vertical displacements play a significant role in the deformation of this salt-controlled basin. Salt stocks are uniformly rising in their crestal domain (up to 8 mm/yr) with lateral spreading along their flanks (1–2 mm/yr). The larger salt walls are more active and rising faster (8 mm/yr) than smaller ones (3 mm/yr), while welded areas are inactive. These rising salt diapirs are flanked by seasonal depocenters accumulating up to 10 mm/yr of fluvial, evaporitic, and aeolian deposits.

近年来，盐扩散器已广泛用于储气，危险废物处置，采矿和石油生产。在计划这些工业利用之前，盐结构中主动运动的速率和模式是至关重要的。伊朗高原的中部盆地代表了暴露良好且保存完好的底栖动物，可以被视为世界上其他暴露程度不佳的其他盐盆地的类似物。干涉合成孔径雷达（InSAR）技术与遥感结构图的集成使我们能够研究伊朗中部Kalut盆地八个盐底盘的活动表面变形。我们将Kalut diapiric结构分类为盐墙，地块，毛坯和焊缝。然后，我们使用从2014年11月至2018年11月的升序采集的75个单一外观复杂（SLC）IW场景，以及从2014年10月至2018年1月采集的降序几何图形的62个SLC图像，均涵盖了同一时期。Sentinel-1图像通过小型BAseline子集（SBAS）方法进行处理，以定义垂直和水平位移图，揭示了Kalut盆地是当今世界上最活跃的双底栖生物系统之一，它的八个盐底栖生物正在上升，但都没有消退。计算出的最大垂直生长速率在垂直方向上达到8毫米/年，在水平方向上达到2毫米/年，这表明总体而言，垂直位移在该盐控盆地的变形中起着重要作用。盐类储量在其地壳区域内均匀上升（最高8毫米/年），并沿其侧面（1-2毫米/年）横向扩展。较大的盐壁比较小的盐壁（3毫米/年）更活跃，上升速度更快（8毫米/年），而焊接区域不活跃。这些上升的盐底物两侧是季节性沉积中心，每年堆积的河流，蒸发和风成沉积物高达10毫米/年。
