Evidence from collision zones suggests that the high temperatures that create regional zones of metamorphic minerals occur in wide, hot back arcs prior to continental collision deformation.
Yoshio Fukao was awarded the 2018 Inge Lehmann Medal at the AGU Fall Meeting Honors Ceremony, held on 12 December 2018 in Washington, D. C. The medal is for “contributions to the understanding of the structure, composition, and dynamics of the Earth’s mantle and core.”
Magnetic and electric field measurements at Earth’s surface provide information on Earth’s interior and on space weather. An open-source central repository of these data has received a major update.
Jie Deng and Ross Maguire will receive the 2018 Study of the Earth’s Deep Interior Award for Graduate Research at AGU’s Fall Meeting 2018, to be held 10–14 December in Washington, D. C. This award is given annually for advances that contribute to the understanding of the deep interior of the Earth or other planetary bodies using a broad range of observational, experimental, and/or theoretical approaches.
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.
The amount of CO2 segregated from the mantle by carbonate melting beneath old oceanic crust may equal that emitted along the mid-ocean ridge system, thereby contributing to the global carbon cycle.
Study bolsters hypothesis that volcanoes on China’s Hainan Island were formed by a hot spot.
By keenly probing mantle rheology, interactions of deformations and phase transitions, and microscopic features, he made major contributions to petrology, mineralogy, and earthquake science.
A high-pressure form of ice, trapped within diamonds forged in the lower mantle, suggests that aqueous fluids reside deeper in Earth than we knew.
A global characterization of mantle flow patterns beneath active oceanic transforms suggests pervasive upwelling stabilizes divergent plate boundaries by warming and weakening these enigmatic features.
