How Is Gold Formed and Where Does it Come From?
Gold isn't truly formed—at least, not on Earth. Gold Comes From Outer Space. Gold, the shiny yellow metal prized for its beauty and malleability and used in many different industries, is actually created inside massive stars when they explode into a supernova. Of course, after a star supernovas and forms gold, the precious metal has to ...

The region is divided into the Inner Zone, formed by complex faulting, and the Outer Zone, formed by warping. The Inner Zone is chiefly composed of ancient granites, rocks of Paleozoic age (250 to 540 million years old), and geologically more recent volcanic rocks, which are arranged in complicated juxtaposition.
