Known processes to remove sodium from the oceans account for only 27
percent of the sodium that is added. Given the accumulation of sodium
this implies, the oceans could not be more than 62 million years old.

Response:
Austin and Humphreys greatly underestimate the amount of sodium lost in
the alteration of basalt. They omit sodium lost in the formation of
diatomaceous earth, and they omit numerous others mechanisms which are
minor individually but collectively account for a significant fraction
of salt.
A detailed analysis of sodium shows that 35.6 x 1010 kg/yr
come
into
the ocean, and 38.1 x 1010 kg/yr are removed (Morton 1996).
Within
measurement error, the amount of sodium added matches the amount
removed.
