Science : Boston University’s Matthew Jackson and his collaborators have analyzed the helium isotope content of lava that spewed onto the surface of Canada’s Baffin Island 62 million years ago. Based on their analysis, which was published today in Nature , the geophysicists conclude that the lava is 4.5 billion years old and must therefore have originated from a deep pool of magma that had escaped adulteration for the rest of Earth’s life.
