Processing of the ore can sometimes lead to the peeling off or "scrolling" of the surface layers at the edges of crystals forming fibres (Chatfield and Lewis 1980). Parallel fracturing and splitting of vermiculite flakes can also lead to the formation of fibre-shaped fragments. Vermiculite scrolls may be very fine (< µm diameter) but the vermiculite fragment fibres tend to be fairly …

Vermiculite is a clay mineral that is generally used for a wide range of applications such as in agricultural, horticultural and construction industries.
