Earth’s oldest known piece of continental crust dates to the era of the moon’s formation.
Australia holds the oldest continental crust on Earth, researchers have confirmed, hills some 4.4 billion years old.
Trees that traveled to space now live on Earth.
Where is the oldest crust found?
Most oceanic crust is less than 200 million years old, because it is typically recycled back into the Earth’s mantle at subduction zones (where two tectonic plates collide). But a new study shows that part of the eastern Mediterranean Sea may contain the oldest known oceanic crust.
Where is the oldest crust in the Atlantic?
The oldest large-scale oceanic crust is in the west Pacific and north-west Atlantic — both are about up to 180-200 million years old. However, parts of the eastern Mediterranean Sea are remnants of the much older Tethys ocean, at about 270 and up to 340 million years old.
Where was the oldest rock found?
Jack Hills, Australia, where rocks were found to contain the oldest known minerals on Earth, a 4.4 billion-year-old zircon. Just three of the very oldest zircons have been found, ones that date back to almost 4.4 billion years ago. Their extreme age always makes the dates suspect, because of possible radiation damage.
