A machine learning model trained using data on the chemical composition of magmatic rocks yields comparable, if not better, results to previously developed geochemical proxies.
Scientists have found holes filled with minerals that indicate fluid-filled pores exist many tens of kilometers below Earth’s surface. But no, The Core fans, you still can’t get amethyst-laden geodes in the mantle.
Using Garnets to Explore Arc Magma Oxidation
Samples collected from Greece help researchers piece together a scientific puzzle.
Understanding Electrical Signals from Below Earth’s Surface
A new version of a free Web application (SIGMELTS 2.0) helps Earth scientists interpret electrical anomalies in Earth’s crust and mantle and track the sources of earthquakes and volcanic eruptions.
