In this particular borehole, scientists only found granite, and no basalt, even as far down as the base of the hole. Researchers deduced that the change in seismic waves might suggest different entirely than the move from granite to basalt, and in fact found that it was the result of metamorphic differences in the rock. In doing more tests, they soon found something even more astounding. Where no one had previously thought possible, so far beneath the depths of the Earth, they found flowing water.
