Petrified Wood - Fossilised Specimen
Petrified wood specimen
Petrified wood specimen from Indonesia. Myocene period, approximately 20 million years old.
In the late Tertiary period, blankets of rainforest surrounding volcanoes were plentiful in Indonesia. After volcanic eruption, these trees were buried by ash and lava, eliminating microbes that would rot the wood. The wood was then replaced with silica rich minerals such as chalcedony, quartz, calcite, opal and jasper. These trace elements impart the beautiful colours in the petrified wood. Traces of manganese impart blue and black colours, while iron traces result in different shades of brown and orange.
Specimen size: 20cm x 12 cm
