Fig. 2 shows a typical flat surface region of vermiculite before and after treatments with water and argon, respectively, which produced the highest topography modifications. Like in muscovite, the crystal surface was clearly etched and the averaged roughness increased for the entire specimen, indicating that the ion gas treatment can be used to modify surface features of layered silicates.
