Maybe something that only interests me, but, science is cool, and we all need a break from politics now and then
The discovery of rocks as old as 4.28 billion years pushes back age of most ancient remnant of Earth’s crust by 300 million years.
McGill University researchers have discovered the oldest rocks on Earth – a discovery which sheds more light on our planet’s mysterious beginnings. These rocks, known as “faux-amphibolites”, may be remnants of a portion of Earth’s primordial crust – the first crust that formed at the surface of our planet.
The ancient rocks were found in Northern Quebec, along the Hudson’s Bay coast, 40 km south of Inukjuak in an area known as the Nuvvuagittuq greenstone belt.
The previous oldest Earth rock was 3.96 billion years old. You can see, and touch, a piece of it at the Smithsonian Museum of Natural History. They have also just added a new piece from the same area, but looks a bit different.
