C-81 “GSSP Chibanian” geomagnetic reversal stratum & Yoro Ravine


C-81 “GSSP Chibanian” geomagnetic reversal stratum & Yoro Ravine

Discovering the mystery of the earth!

Chibanian, which was inscribed into the geological chronology used around the world on January 2020!

Golden Spike of GSSP

What is “Chibanian”?

The earth, which has a long history of 4.6 billion years since its birth, is divided into several eras. The Jurassic and Cretaceous periods, when dinosaurs lived, are well known. Most eras have already been named, but some eras have not yet been named.

Fossils have been used to identify major global events, such as the emergence and extinction of organisms, when determining the age of the Earth. Recently, the period when the geomagnetic field reversed was also used.

The stratum in Ichihara City, Chiba Prefecture has the best record of the latest geomagnetic reversal in the world, and this stratum was approved as an international boundary type site (GSSP: Global Boundary Stratotype Sections and Points) for the Early and Middle Pleistocene geological ages, and recognized worldwide. This is Japan’s first GSSP.

As a result, the period from about 774,000 years ago to 129,000 years ago, which until now had no name, came to be called “Chibanian”, which means “the age of Chiba” in Latin. This is the first time that a geological age has been named after a place in Japan !

Chibanian” geomagnetic reversal stratum

What is geomagnetic reversal?

The N (magnetic) pole of a compass always points north. This is because the earth itself is like a big magnet. The earth’s magnetic field is called geomagnetism.

At the present, the north pole is the S magnetic pole, and the south pole is the N magnetic pole, but we know that the Earth’s long history has reversed many times. Over the last 3.6 million years, it is said that there have been more than 10 reversals. However, it is not yet clear why the reversal occurs.

A story of geology is hard to imagine just by hearing.
By actually going, seeing, touching, and experiencing, the knowledge you have learned will further broaden your scientific perspective.
Why don’t you visit it once?


Yoro Ravine

Chiba Prefecture has a strong image of the sea, but Yoro Ravine, which flows almost in the center of the Boso Peninsula, is dotted with numerous waterfalls and also famous as a power spot.

The area around the Yoro River called “Yoro Ravine” is one of the best hot spring villages in Boso. The beautiful fresh greenery from spring to early summer, and the colored leaves in autumn are spectacular, attracting many tourists.

After discovering the mysteries of the earth, let’s refresh yourself with the minus ions fill in Yoro Ravine!

Autumn is the best season!
