Polarised light micrograph of a thin section showing the complex details of precipitation and crystallization inside a small geode, with banded rings of chalcedony on the periphery and a core of crystalline quartz. The colours are a consequence of the transmitted light being polarised. Actual width of specimen tip to tip is 55 mm. | |
