Figure 2From: The mineralogy and space weathering of a regolith grain from 25143 Itokawa and the possibility of annealed solar wind damageWeak-beam dark-field TEM image of an olivine subgrain in subsample 03. A high density of mixed screw- and edge-type [001] dislocations (g = 222) is visible. Also visible is the strongly diffracting nanocrystalline olivine rim at the surface of the particle (arrows).Back to article page
