Deepest Drill into Earth's Mantle
An international team of geologists achieved a significant milestone by drilling 4,160 feet deep into the Earth's mantle, surpassing the previous record of 659 feet. This drilling took place at the Mid-Atlantic Ridge, where tectonic activity has made the mantle more accessible. They successfully recovered 70% of the rock samples, revealing unexpected findings such as serpentinized rock, which indicates a chemical interaction between seawater and mantle material. These discoveries suggest that the boundary between the crust and the mantle may not be as distinct as previously believed, opening new questions about Earth's geochemical cycles.
