Fig. 2: 3D reconstructions of fractures and magnetite veins in perspective view created from nano-CT data.
From: Evidence from 162173 Ryugu for the influence of freeze–thaw on the hydration of asteroids

Fractures are shown in black and magnetite veins in blue. Both fractures and magnetite veins have curved, intersecting morphologies dominated by cuspate forms. Some magnetite veins are cut by fractures; others are subparallel. Lines have been added to emphasize the 3D shape and intersection of features. a and b show fractures, while c and d also include magnetite veins. a and c are projected from the left, while b and c are projected from the front.
