A new study shows that water was transported much deeper in the early earth than previously thought.
Most of the gold mined in the Fimiston open pit, pictured here, occurs within ore lodes formed by ancient shears in a rock unit called the Golden Mile Dolerite.Researchers at Curtin University discovered that water was transported much deeper in the early earth than previously thought, a finding that sheds new light on how continents were originally formed.
“This water, which is locked into particular crystals within the rock, would have been released as the rocks were buried and began to ‘sweat.’ In modern lavas, this sweating happens at a temperature of about 500 degrees Celsius,” the scientist said. According to Hartnady, this means that the water was transported much deeper into the early earth than previously thought and that its release would have caused surrounding rocks to melt, ultimately forming continents.
