When water met iron deep inside the Earth, did it create conditions for life
Washington DC (SPX) Nov 16, 2017
Reservoirs of oxygen-rich iron between the Earth's core and mantle could have played a major role in Earth's history, including the breakup of supercontinents, drastic changes in Earth's atmospheric makeup, and the creation of life, according to recent work from an international research team published in National Science Review. The team - which includes scientists from Carnegie, Stanford University, the Center for High Pressure Science and Technology Advanced Research in China, and the Universit ... read more
