Fossilised Wood (Petrified
Forests)
Age: Upper Triassic, Approx 170 -
225 million years old
These are ancient tree trunks that has been
turned to stone. These ancient trees lived in
a region which had a moist and probably warm
climate. Washed from upland areas where they
grew, the logs accumulated on the delta flats
where they where buried by sand and silt and
layers of volcanic ash. This ash was the source
of silica which helped to mineralize the logs
after burial. The logs where replaced by quartz
or silica coloured with oxides of iron and
manganese. |
