FIND a fault in the earth’s crust and you could find some gold, West Australian researchers say. After studying the St Ives Goldfields in WA, researchers concluded small-scale fault systems had a strong correlation with the location of gold.

In doing so, their study suggests strongly a continental crust was present on Earth about 100 million years after the planet formed. And by implication, it tells us that if temperatures were low enough, it could have perhaps even sustained.

Groundwater is very heavy, and its weight depresses the Earth’s upper crust. Remove the weight, and the crust springs upward. The study, published online Thursday by the journal Science, showed how a lack of rain and snow cut water.

The new study, published in the journal Nature Geoscience, found that if you exclude the water frozen in glaciers or ice caps, 95 percent of the planet’s freshwater is in Earth’s crust. <img class="styles-A54tP4F3__noscript__12c_l".
