The name “Chibanian,” based on a stratum discovered in Chiba Prefecture, is set to represent the geological age when the latest reversal of the Earth’s magnetic fields is believed to have occurred, a Japanese national research institute said Monday.

The National Institute of Polar Research said the term meaning “Chiba age” garnered more than 60 percent of votes, beating “Ionian,” a name related to stratums in Italy, for a geologic time period from 770,000 to 126,000 years ago in the first screening process at an international academic society.
