Three naturally occurring allotropes of carbon are known to exist: amorphous, graphite and diamond.
Thus radioactive dating relies purely on assumptions.
Figure 3(b) Closer view of the quarry face of the south wall showing the oxidized limestone of the top of the Marlstone Rock Bed which is quarried as ‘Hornton Brown’ building stone. During two visits to the Hornton Quarries, it was established that fossil wood occurs alongside ammonite and belemnite index fossils (see aside below) in the ‘Hornton Stone’, the oxidized silty top of the Marlstone Rock Bed.
The ammonite recovered in the quarries is Many such belemnite fossils had been found during quarrying operations (Figure 6).
