eon |
geology The largest unit of the geochronologic scale, being often thought of as a billion (109) years (and proposed by Gamow to be exactly that
[Gamow G. Nature Vol. 219, 765 (1968)]). Deriving etymologically from ‘life’, eon, in the form of the current eon (the Phanerozoic, lasting about 570 million years), encompassed the whole fossil record when it was introduced. Preceding time was lumped together as the undifferentiated lifeless ‘pre-Cambrian’ eon of 4 billion years. Now that too is seen as including life, and is divided. The next smaller unit is era.
