Oxyhydroxides like δ-(Al,Fe)OOH are arguably the main hosts of water in the lower mantle. Therefore, constraints on the single-crystal elastic tensor of δ-(Al,Fe)OOH solid solutions are crucial to quantify the elastic anisotropy of this material, and advance the current understanding of the recycling of water into the lower mantle. Yet, experimental data for intermediate compositions are scarce, limiting the understanding of how Fe incorporation affects the single-crystal elastic properties of δ-AlOOH. In this study, we provide experimental constraints on the single-crystal elasticity of two δ-(Al,Fe)OOH solid solutions, with Fe/(Al + Fe) of 0.06(1) and 0.133(3). Large single-crystal samples of δ-(Al,Fe)OOH were synthetized at high pressures and temperatures using a multi-anvil press, and the full elastic stiffness tensors were determined at ambient conditions by combining X-ray diffraction and Brillouin scattering measurements. We show that replacing Al³⁺ with Fe³⁺ in δ-(Al,Fe)OOH lowers the magnitude of most coefficients of the elastic stiffness tensor (<i>c</i>_ij), which translates into a substantial reduction of aggregate moduli and acoustic wave velocities. We further show that, at ambient conditions, the acoustic anisotropy of δ-(Al,Fe)OOH displays no sensitivity to Fe–Al substitution.</p></div>","PeriodicalId":20132,"journal":{"name":"Physics and Chemistry of Minerals","volume":"52 2","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00269-025-01319-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143848971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This implies that the pressure stability of the M2 octahedra in the Al-rich phase D is higher than that in the pure-Mg phase D due to the substitution of Al³⁺ for Si⁴⁺. The major OH band at about 2900 cm^− 1 in the Raman spectra of the pure-Mg phase D sample shifts continuously toward higher frequencies with increasing pressure due to the pressure-induced transition from straight H bonds to bent ones.

Interpretation of the melting behavior is however challenging because extreme temperature gradients are inevitable. In this work, we investigate how the peak temperature at the center of the laser spot, from sample solidus to 1000 K above (ΔT), affects the chemical relations between melt and solid residue. We investigate the melting behavior of two possible mantle compositions, pyrolite and chondritic type material, at pressures corresponding to depths of ~ 1000 km and higher (40–73 GPa). Recovered samples are characterized at nanoscale spatial resolution using electron microscopy. Samples tend to show that chemical composition of melts and bridgmanite-melt relations vary largely with peak temperature. With increasing ΔT, the (Mg,Fe) exchange coefficient (K_Fe-Mg^Bg/melt) decreases from 0.29 to 0.11, and SiO₂ contents in melt ([SiO₂]^melt) from 43 to 18 wt%. In addition, we observe that the higher ΔT, the more the liquid is depleted in bridgmanitic-type composition. These experimental features are contrary with those expected from the known melting diagram of typical mantle material. Instead, they are well explained by considering fast solidification of bridgmanite (Bg) at the edge of the molten zone, in disequilibrium conditions. The sample prepared at solidus temperature and for short duration presents a central melt pool of Ca-bearing melt in close contact with Bg and ferropericlase. The degree of partial melting is coherently estimated to 18(2) wt% by two independent observations. This corresponds to pseudo-eutectic conditions where only the third mineral, davemaoite, is exhausted. For a pressure of 40.5 GPa, K_Fe-Mg^Bg/melt and [SiO₂]^melt are found to be 0.29 and 43 wt%, respectively, in good agreement with multi-anvil press experiments.
