## Description

- description: The cross-section of thermally exfoliated “Vermiculite” was investigated
    using thin sections made by the novel dry-polishing method.  Two samples of “Vermiculite”
    from Palabora, the Republic of South Africa, and from Ono-machi, Fukushima, Japan,
    were used as starting materials. The “Vermiculite” was flash-heated at 900ºC and
    kept for 30 minutes, and then quenched to the ambient condition. The sample before
    and after heating was checked by the powder XRD method. The thin sections of the
    exfoliated “Vermiculite” were observed by optical microscopy. The exfoliation
    structure is the combination of 2 types of pore structure with different dimensions.
    The first one is the aggregation of the expanded structures related to the mosaic
    distribution in a few hundred m of the different clay minerals within the particle,
    which is consistent with the results by Hiller et al. (2013). The second one in
    mm-scale is the aggregation of spindle-shaped pore structure, which is assembled
    by the first pore structure. The whole exfoliation structure is related to the
    domain structure of the original biotite.
