Abstract: Abstract The lower mantle is believed to contain much less hydrogen (or H2O) because of the low storage capacity of the dominant mineral phases, such as bridgmanite and ferropericlase. However, possible hydrogen storage in the… read more here.

Abstract: Tschauner et al. (Reports, 11 November 2021, p. 891) present evidence that diamond GRR-1507 formed in the lower mantle. Instead, the data support a much shallower origin in cold, subcratonic lithospheric mantle. X-ray diffraction data… read more here.

Abstract: Abstract Earth’s mantle convection is powered in part by the radiogenic heat released by the decay of 238U, 235U, 232Th, and 40K. We present ab initio calculations of uranium and thorium incorporation in CaSiO3-perovskite with… read more here.
