Abstract
The article discusses the discovery of rocks in the Nuvvuagittuq Greenstone Belt (NGB) in northern Quebec, Canada, which researchers claim may be the oldest known on Earth, dating back at least 4.16 billion years. This finding, if confirmed, would provide insights into the Hadean Eon, the earliest period of Earth's history. Previous dating methods yielded conflicting ages, but recent studies using isotopic dating of ancient magma intrusions have produced consistent results supporting the rocks' extreme age. The research highlights the significance of these ancient rocks in understanding the early chemical and structural state of the Earth. [Extracted from the article]
