[Tomo]: Crystalline sample. Very small grains of heavy minerals (Fe sulfide or magnetite?: metal is also possible) are present along the grain boundaries of silicates. Portions which seem to be mesostasis are also seen. If this is mesostasis, this sample has prophyritic texture. Small voids are also present. The particle is partially covered with a porous (aerogel + sample?). Fractured surface without covering the porous material is also seen.
