Wrong Assumptions

So, in this case, the researchers discovered that only granite existed. So even at the deepest point of the borehole, there were only graphite rocks present. Ultimately, the researchers could then conclude that the change in seismic waves had been caused due to the metamorphic differences in the rock. It was actually not because of the shift to basalt. Their predicaments had all proven to be wrong so the researchers were more than ever, ready to clarify this confusion.
