Lodranite (3D recon)

3D reconstructions of meteorite GRA95209. Metal "cap", veins and dikelets are opaque orange-yellow. Groundmass (of fine-grained metal particles and silicates) has been rendered transparent to show distrubution of metal grains within the sample. Metal-poor silicate-rich areas appear blue. The images record a complicated and intriguing picture of melt generation and migration in the lodranite parent body, a primitive planetisimal that is one of the best existing models for processes occuring during core-mantle segregation in the terrestrial planets.
