The World's Oldest Mineral

The world's oldest mineral is zircon, found from the Jack Hills conglomerate in Western Australia. One small spot of a 4.3 billion years old zircon has been dated to an age of 4.4 billion years and this led to an announcement in 2001 that the primitive continental crust was formed as long as 4.4 billion years ago.
