Short summary
Short summary
Three-dimensional backstripping based on the Archimedes principle restored changes through time in 3D subsurface evaporite thickness, 3D salt loss and gain, and 3D subsurface salt movement. The methodology presented is sensitive to any process that influences overburden thickness, in this case sedimentation, erosion and tectonics. The restoration approach can be integrated into existing backstripping workflows and can serve as a benchmark for physics-based numerical modelling of salt tectonics.

Short summary
This paper uses seismic reflection methods to image and better constrain fault and basin architecture at depth in a region of northern Australia thought to be highly prospective for oil and gas as well as sediment-hosted lead–zinc mineralisation. A better understanding of these architectural constraints is essential for the delineation of fluid pathways, barriers, and potential traps where these commodities may have accumulated.
