What They Discovered
At the farthest reaches of the Kola Superdeep Borehole, an even more exciting discovery was made. Experts had previously predicted that the rock beneath our feet was moving from granite to basalt at around two to four miles below the surface by calculating seismic waves. However, they soon discovered that this was not the case, at least not on the Kola Peninsula.
What They Discovered
Only Granite
Instead, researchers found only granite, even at the deepest point of the borehole. They were finally able to infer that the change in seismic waves, rather than a transition to basalt, was the result of metamorphic changes in the rock. But it wasn’t that, either. Amazingly, several miles below the Ground, at depths where nobody predicted it would occur, they have found flowing water.
