The Geologic Time Scale (GTS), like the Earth Epic Calendar, has the Eon as its largest unit of measure. But the GTS is based on stratigraphy and significant moments in Earth history, as opposed to precise lengths of time. The “Geologic Eon” ranges in length from 500 million to 2 billion years. Examples of the Geologic Eon are the Hadean ...EON claiming will be available from 18:00 Jun 14, 2018 (Hong Kong time). To claim your EON, please go to "Account > My Wallet > EON" and select "Claim".

It signifies an indefinitely long period, often used to describe billion-year timescales in the field of geology and cosmology . Eons are divided into eras, which are further segmented into periods, epochs, and ages.
Hadean Eon, informal division of the Precambrian occurring between about 4.6 billion and about 4.0 billion years ago.

The oceans were also largely anoxic - with the possible exception of O 2 in the shallow oceans.Geological time has been divided into four eons: Hadean (4570 to 4850 Ma), Archean (3850 to 2500 Ma), Proterozoic (2500 to 540 Ma), and Phanerozoic (540 Ma to present). As shown in Figure 8.1.2, the first three of these represent almost 90% of Earth’s history.

Geologic Time Scale. Humans subdivide time into useable units such as our calendar year, months, weeks, and days; geologists also subdivide time. They have created a tool for measuring geologic time, breaking it into useable, understandable segments. For the purposes of geology, the “calendar” is the geologic time scale.
Proterozoic Eon. The Proterozoic Eon is the second and the last of the three eons of the Precambrian era and covers the time interval between 2.5 billion and 541 million years ago. It follows the Archean Eon and precedes the Paleozoic Era. The Proterozoic Eon was a time of significant change and evolution in the history of the Earth.A major division of geological time, hundreds of millions to a billion of years long, usually distinguished by significant changes in the plant and animal kingdoms. There are four major divisions: Precambrian, Paleozoic, Mesozoic, and Cenozoic. Greek: paleo= "Old"; meso= "Middle"; ceno= "Recent"; zoic= "of life".Aug 3, 2023 · Definition of Eon “Eon,” also spelled as “aeon,” refers to the largest division of the geologic time scale, superseding eras.
