      Fonseca, Raúl O. C.ORCIDiD; Michely, Lina T.; Kirchenbaur, Maria; Prytulak, Julie; Ryan, Jeffrey; Hauke, Kerstin; Leitzke, Felipe P.; Almeev, Renat R.; Marien, Chris S.; Gerdes, AxelORCIDiD; Schellhorn, Rico (Contributions to Mineralogy and Petrology, 2020-12-23)
      The Izu–Bonin–Mariana volcanic arc is situated at a convergent plate margin where subduction initiation triggered the formation of MORB-like forearc basalts as a result of decompression melting and near-trench spreading. ...
    • The redox dependence of titanium isotope fractionation in synthetic Ti-rich lunar melts 

      Rzehak, Laura J. A.ORCIDiD; Kommescher, Sebastian; Kurzweil, Florian; Sprung, Peter; Leitzke, Felipe P.; Fonseca, Raúl O. C.ORCIDiD (Contributions to Mineralogy and Petrology, 2021-02-28)
      Equilibria between Ti oxides and silicate melt lead to Ti isotope fractionation in terrestrial samples, with isotopically light Ti oxides and isotopically heavy coexisting melt. However, while Ti is mostly tetravalent in ...
