Abstract

Secondary ion mass spectrometry measurements show that Earth's representative lower mantle minerals synthesized in a natural peridotitic composition can dissolve considerable amounts of hydrogen. Both MgSiO 3 -rich perovskite and magnesiowüstite contain about 0.2 weight percent (wt%) H 2 O, and CaSiO 3 -rich perovskite contains about 0.4 wt% H 2 O. The OH absorption bands in Mg-perovskite and magnesiowüstite were also confirmed with the use of infrared microspectroscopic measurements. Earth's lower mantle may store about five times more H 2 O than the oceans.
