About this specimen
A single black eye opens in a bed of pale mica. The cassiterite holds the centre of this Xuebaoding plate, a lustrous jet-black group with a near-metallic sheen and fine striations, ringed by champagne-coloured muscovite books stacked in overlapping fans. Around the outer edge, aquamarine crystals push up through the mica — here water-clear rather than blue — with a milky quartz blade at the right margin.
Xuebaoding in Sichuan is the classic source for this three-way association, cassiterite with beryl and muscovite in greisen-altered granite. Cassiterite is tin oxide, SnO2, at Mohs 6 to 7; the muscovite around it is the softest thing here, barely 2. The mica books bruise and flake long before anything happens to the tin oxide, which is what to remember.
The plate measures 6.6 × 5.8 × 3.3 cm and weighs 110 g. No base is fitted, and it looks best with light raking across the mica so the books flash and the cassiterite stays dark. The images on this page were taken of this plate and no other.
