• Oxygen Vacancy Ordering in Aluminous Bridgmanite in the Earth's Lower Mantle 

      Grüninger, HelenORCIDiD; Liu, ZhaodongORCIDiD; Siegel, Renée; Boffa Ballaran, TizianaORCIDiD; Katsura, TomooORCIDiD; Senker, JürgenORCIDiD; Frost, Daniel J.ORCIDiD (Geophysical Research Letters, 2019)
      Oxygen vacancies (OVs), that charge-balance the replacement of octahedrally coordinated Si4+ by Al3+ in the mineral bridgmanite, will influence transport properties in the lower mantle but little is known about their ...
    • Single‐Crystal Elasticity of Antigorite at High Pressures and Seismic Detection of Serpentinized Slabs 

      Satta, NiccolòORCIDiD; Grafulha Morales, Luiz FernandoORCIDiD; Criniti, GiacomoORCIDiD; Kurnosov, AlexanderORCIDiD; Boffa Ballaran, TizianaORCIDiD; Speziale, SergioORCIDiD; Marquardt, KatharinaORCIDiD; Capitani, Gian CarloORCIDiD; Marquardt, HaukeORCIDiD (Geophysical Research Letters, 2022-08-26)
      The subduction of serpentinized slabs is the dominant process to transport “water” into Earth's mantle, and plays a pivotal role for subduction dynamics. Antigorite, the most abundant serpentine mineral in subduction ...
