Microstructural study of rocksalt samples from an active salt fountain (Qum Kuh, central Iran) enabled to identify the relative contribution of different deformation mechanisms on extrusive salt flow. The microstructural study combined reflected and transmitted light microscopy of gamma-irradiated thin sections, textural analysis of digitized microstructures and Electron Back Scattered Diffraction (EBSD). Deformation microstructures record the strongly variable deformation conditions of salt flow in the diapiric system from the diapiric stem towards the distal part of the mature viscous fountain.
