英文摘要 | We show that high‐resolution aeromagnetic surveys, although rarely employed in the research of salt structures, may be an effective and low‐cost tool for mapping diapirism. A multiscale analysis of a high‐resolution magnetic dataset at Nordkapp Basin in the Barents Sea, allows a clear reconstruction of the main salt diapirs of the basin using Multiridge and Compact Depth from Extreme Points methods. We provide a 3D model of the diapirs extended from 500 m to 4000 m below sea level, characterized by a general low magnetization contrast no larger than ‐0.08 A/m. The 3D model is consistent with the salt top depth estimated by 2D seismics, with borehole data and with the 2D gravity model of the Uranus diapir. Our imaging shows the capability of the magnetic method that gives new and comprehensive pictures of salt diapirism. |
