Oct 5, 2021 · The divisions of the geologic time scale are organized stratigraphically, with the oldest at the bottom and youngest at the top. GRI map abbreviations for each geologic time division are in parentheses. Boundary ages are in millions of years ago (mya). This timeline gives a chronological listing of all Geological Time Periods, Eras and Eons from 4600 million years ago to present day HADEON EON 4600 – 3900 million years agoOverall, Florida's geological history has been driven by changing sea levels, which have influenced the production of carbonate bedrock, siliciclastic input/transport, hydrology, and surface topography. During the last interglacial period, the majority of south Florida was a shallow carbonate environment with some siliciclastic input.
