Abstract
Until recently, most geologists would have considered the birth of the solar system, and with it the origins of our home planet, to lie outside the reach of their field. It is true of course that some pioneering geochemical studies established an approximate age for the earth, using ingenious indirect means, some time ago (e.g. Allègre et al., 1995), but a formal name for our planet’s early years has been a long time coming. The reason for this oversight is largely because the global body that formalises the subdivision of time and strata, the International Commission on Stratigraphy or ICS, has quite understandably focussed on earth’s rock record. Unfortunately, there are no rocks from the first one tenth of our planet’s existence, at least not on Earth, with the exception of meteorites.
