Thin section polarised light micrograph showing the complex details of precipitation and crystallisation inside a small geode, with banded rings of chalcedony on the periphery and a core of crystalline quartz. The strong colouring is a consequence of the transmitted light being polarised. Actual size is 32 x 40 mm.
