Sealing The Kola Borehole
Even though the project dubbed the Kola Superdeep Borehole had been forced to shut down its operations due to limitations of knowledge and equipment, that doesn’t mean the researchers didn’t make sure to collect as much data as they possibly could before it was sealed up. One example is a discovery of tiny marine plant fossils, about four miles deep into the borehole. Any archeologist would call these fossils a rare sight, and researchers were stunned that they had been entombed in the rock estimated to be billions of years old at the time.
