How did gold appear on Earth?
Gold came to Earth billions of years ago from space in a number of ways, including:
Meteorite bombardment
Gold-rich meteorites hit the Earth, embedding gold in the planet's crust over time.
Collision with large space bodies
When the early Earth collided with large, moon-sized space bodies, the resulting deposits of materials included gold.
Supernova explosions
Gold is thought to have been produced during supernova explosions billions of years ago.
Neutron star collisions
Gold may also have been produced by the collision of neutron stars.
Subduction
The first plate tectonics and subduction occurred around 3 billion years ago, generating water and silica-rich magmas that concentrated and deposited gold in veins.
Volcanic eruptions
Volcanic eruptions brought gold directly to the surface, where it was usually deposited in rivers and streams.
