Application of the SAR interferometric methods to identify the mobility of the area above the salt diapir in Inowrocław and the regional salt structures in central Poland

Abstract

Remote sensing interpretation presents the linear structural elements correspond to the tectonic-structural pattern and suggest a block-type character of the pre-Permian basement. They may also indicate the existence of active movements of salt bodies and point at tectonic zones being active during almost recent past. The research on terrain mobility in the Inowroc aw salt dome area and regional salt structures was conducted with the use of SAR interferometry techniques: PSI and InSAR. All archival scenes (both descending and ascending) available from satellites ERS-1/2 and ENVISAT were used in order to determine the nature of displacement during the last 15 years. To identify the mobility of the pilot study, locally and regionally, the results from SAR interferometry techniques were analysed together with all types of collected data: tectonics, geophysical, geological, geodetic, and structural data. That gave indications about the uplift and subsidence in the salt dome area, as well as information about the types and causes (natural and induced) of mass movements.
