Discovery
The researchers found out that the rock became less dense the deeper they drilled. This allowed it to react very unpredictably to the higher temperatures at great depths. Because the scientists’ equipment could not withstand this degree of unpredictability, they decided to stop the project. This decision was made in 1992, 22 years after they began their drilling attempt.
But before they closed the so-called Kola Superdeep Borehole, scientists posted at this location got the opportunity to gain a wealth of knowledge about the secrets lurking in the depths of our globe. Curious about what they discovered at these unimaginable depths? Read on quickly!
