Like a mosquito tunneling into the skin to get at the rich feast within, geologists poked a long, narrow drill into Earth's crust last year, pulling out a treasury of geological goodness. The result ...

Gold and other precious metals are leaking from Earth’s core into the layers above, eventually making their way up to the surface during the formation of volcanic islands like Hawaii, a new study ...

Barbara John, left, a professor in the UW Department of Geology and Geophysics, and Frieder Klein, from Woods Hole Oceanographic Institution, describe core hosting some of the mantle rocks recovered ...

The Earth's mantle might not always move along in lockstep with the overlying tectonic crust—as set out in science textbooks for decades—but may instead behave differently. This is the conclusion of ...
