Blocked radiative heat transport in the hot pyrolitic lower mantle
Sergey S. Lobanov, Nicholas Holtgrewe, Gen Ito +8
The heat flux across the core-mantle boundary (QCMB) is the key parameter to understand the Earth/s thermal history and evolution. Mineralogical constraints of the QCMB require dec…
Opaque Lowermost Mantle
Sergey S. Lobanov, François Soubiran, Nicholas Holtgrewe +3
Earth/s lowermost mantle displays complex geological structures that likely result from heterogeneous thermal and electromagnetic interaction with the core. Geophysical models of t…
Raman spectroscopy and X-ray diffraction of sp3-CaCO3 at lower mantle pressures
Sergey S. Lobanov, Xiao Dong, Naira S. Martirosyan +8
The exceptional ability of carbon to form sp2 and sp3 bonding states leads to a great structural and chemical diversity of carbon-bearing phases at non-ambient conditions. Here we…
Optical signatures of low spin Fe3+: a new probe for the spin state of bridgmanite and post-perovskite
Sergey S. Lobanov, Han Hsu, Jung-Fu Lin +2
Iron spin transition directly affects properties of lower mantle minerals and can thus alter geophysical and geochemical characteristics of the deep Earth. While the spin transitio…
Radiative conductivity and abundance of post-perovskite in the lowermost mantle
Sergey S. Lobanov, Nicholas Holtgrewe, Jung-Fu Lin +1
Thermal conductivity of the lowermost mantle governs the heat flow out of the core energizing planetary-scale geological processes. Yet, there are no direct experimental measuremen…
Reduced radiative conductivity of high and low spin FeO6 octahedra in the Earth's lower mantle
Sergey S. Lobanov, Nicholas Holtgrewe, Alexander F. Goncharov
The ability of Earths mantle to conduct heat by radiation is determined by optical properties of mantle phases. Optical properties of mantle minerals at high pressure are accessibl…
