Arctic rocks may contain oldest remnants of Earth (BBC)
By Howard Falcon-Lang
Science reporter

Scientists have found Arctic rocks that may preserve the earliest remnants of Earth.

Over billions of years, much of the material that made up the early Earth was modified by processes such as melting and mixing.

But the Arctic rocks seem to contain chemical signatures that date from just after the Earth's violent origin.

If confirmed, the discovery challenges established theories about the formation of our planet.
***
The signatures found in Arctic lavas are more than 4.45 billion years old. By comparison, the Earth is 4.54 billion years old, only slightly older.
