samples of pre- and postseismic<br />
event samples from<br />
different areas of <strong>the</strong> cave.<br />
Four of <strong>the</strong> samples are type<br />
A seismite samples (Fig. 23).<br />
This isochr<strong>on</strong> calculated age<br />
is c<strong>on</strong>sidered to be very<br />
accurate since it is derived<br />
from five DN-7 post-seismite<br />
samples, which is a type A<br />
seismite (Fig. 23).<br />
