The Chaotian Eon

Formation of the Solar System

Proposed time scale for the Solar System formation and the early Earth, from Goldblatt et al. 2010 p.2; Creative Commons attribution license.

This very brief unit is concerned with the formation of the Solar System, up to the formation of the Earth, it represents a convergence and overlap of cosmology with geology (timescale), as shown by the dual menu hierarchies above. Our inspiration here is an intriguing suggestion by Goldblatt et al. 2010, to extend the geological timescale further back so that a new eon, called the Chaotian now precedes the Hadean (see diagram at right). Although this is getting into pretty speculative territory, it looks like fun, so why not? MAK110725
