Extended Data Fig. 5: Windrose diagram of fractures’ azimuth in low- and high-boulder density regions and where a second fracture identification was performed.
From: Alignment of fractures on Bennu’s boulders indicative of rapid asteroid surface evolution
In (a), black- and grey-lined rectangles show, respectively, the regions of high and low boulder density, according to Fig. 2 of ref. 15 where the corresponding windrose diagrams of fractures’ azimuth where calculated (displayed on the right side of each area). (b) Map of the seven rectangular regions within which a second co-author performed an independent fracture identification and mapping. The windrose diagram of the azimuth of the fractures mapped in all areas is overlaid on top of the background map.
