a Global context of the 19 crater candidates18 (Supplementary Table 1) and location of provinces and rovers (yellow triangles) referred to in the present study. Background: Mars Orbiter Laser Altimeter (MOLA) shaded relief (https://astrogeology.usgs.gov/search/map/Mars/GlobalSurveyor/MOLA/Mars_MGS_MOLA_DEM_mosaic_global_463m). b, c: Magnetic field intensity and remanent magnetization at the surface from ref. 27. d, e Potassium and Thorium concentration at the surface from ref. 28,30. Beige area corresponds to discarded provinces due to the weathered basaltic surface contribution (Methods).
