We found that the iron-bearing majoritic garnet (Mg 0.79 Fe 0.08 Al 0.30 Si 0.84 O 3 ) remains elastically isotropic throughout the pressure range of this study. The shear and adiabatic bulk moduli and their pressure derivatives at zero pressure were determined to be  µ  0  = 88.7(7) GPa,  K  S0  = 166(2) GPa, (∂ µ  / ∂ P ) 0  = 1.28(8), (∂ K  / ∂ P ) 0  = 4.2(2). These values are almost indistinguishable, within the experimental uncertainties, from those obtained in previous studies of pure MgSiO 3  majorite and other solid solutions of the majorite–pyrope join. Our direct acoustic velocity measurements of iron-bearing majorite indicate that the incorporation of iron into majoritic garnet does not drastically affect its elastic moduli and their pressure derivatives. The measured pressure derivatives of iron-bearing majorite are about 3.6 times lower than required to account for the high seismic velocity gradients observed in the mantle transition zone."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1382544420566918659","@type":"Researcher","foaf:name":[{"@value":"Motohiko Murakami"}]},{"@id":"https://cir.nii.ac.jp/crid/1382544420566918660","@type":"Researcher","foaf:name":[{"@value":"Stanislav V.
