Focusing on the late Archean eon (3 billion years to 2.5 billion years ago), Professor Eiichi Tajika and his team simulated crucial aspects of Earth’s biological, chemical, and geological history.

Tajika and his team used a numerical model to simulate key aspects of biological, geological and chemical changes during the late Archean eon (3.0-2.5 billion years ago) of Earth's geologic history.

The Archean Eon (4–2.5 million years ago) is the second of Earth’s four major geologic eons, a time when the planet was mostly covered by oceans extending far deeper than those found today.

This creates a high entry barrier for new entrants. Archean Chemical Industries (ACI), India’s largest bromine exporter, plans to raise Rs 1,462 crore from initial public offering. Nearly half of the ...
