A New Study Just Revealed That Earth’s Core Is Actually Leaking

Science Alert  July 11, 2019
By looking at very small variations in the ratio of isotopes of the element tungsten, an international team of researchers (Canada, France, USA – UC Davies, Florida State University, UT Houston, Australia) suggests that some core material does transfer into the base of these mantle plumes, and the core has been leaking this material for the past 2.5 billion years. The study gives us a tracer that can be used to investigate core-mantle interaction and the change in the internal dynamics of our planet, and which can boost our understanding of how and when the magnetic field was turned on…read more.
