the hypothesis that hydrothermal circulation
must be severely curtailed during periods of
glaciation because of a limited ground water
recharge. He suggests that the rock/water heat
transfer processes supplying the low-temperature
thermal activity in Iceland today are not a steady
state phenomenon, but of a transient nature,
dating back to the end of the last glaciation about
10,000 years ago. His calculations for various
transient heat transfer models lead to a recharge
area which is an order of magnitude smaller than
the above value.
