Fig. 8From: Geophysical investigation of the Mado Megamullion oceanic core complex: implications for the end of back-arc spreadingGravity features of the surveyed area. a Free-air gravity anomalies with contours of 10 mGal intervals. The data points are shown in gray. b Mantle Bouguer gravity anomalies. White lines show 10mGal-contours. c Inferred crustal thickness variation. White lines show 0.5Â km-contours. The reference crust thickness is 6Â km. d Inferred density variation. White lines show 50Â kg/m3-contours. In b, c, and d, bathymetry contours (black, 200Â m interval) and major morphological features are plottedBack to article page
