Geologists and physicists has created the first global map of antineutrino emissions, published online in the journal Scientific Reports on September 1, 2015. The map provides an image of the energy budget of Earth’s interior.
The neutrino and its cousin the antineutrino, are the smallest known particles.
William McDonough, professor of geology at UMD and a co-author of the study, said:
“The interior of Earth is quite difficult to see, even with modern technology. Locating the activity of antineutrinos allows us to create images that our predecessors had only dreamed of. This map should prove particularly useful for future studies of processes within the lower crust and mantle.”
