A video clip that caught my attention

The clip is about how gold from deep under the earth rose up to form massive deposits in mountains.

  • Plates crush each other in a direction perpendicular to the north-south direction, causing the gold to be pushed up in slits parallel to north south direction. 
  •  When rocks are under incredibly high pressure, they gain a lot of heat and release piping hot fluids.
  • The fluids gather the gold particles and trap them into big clumps of gold when the quartz in the fluid  loses heat and crystallises.
  • Closer inspection can reveal many things.
