| Dutch ..... Eon op de geologische tijdschaal dat vóór het proterozoïcum kwam en ongeveer 1,5 miljard jaar duurde. In deze tijd bestond de atmosfeer van de aarde waarschijnlijk uit methaan, ammonia en andere gassen, en was het oppervlak voldoende afgekoeld om stenen en continentale platen te doen vormen. |
