Fig. 2From: An in situ experimental study of Zr4+ transport capacity of water-rich fluids in the temperature and pressure range of the deep crust and upper mantleExamples of Raman spectra of high-frequency intensity envelope. a Spectra at approximately the same temperature conditions for each of the compositions studied. b Temperature/pressure evolution example from the ZrO2-H2O system. All spectra were normalized to the total integrated area of the 3600 cm−1 envelope. Note that individual spectra are offset for clarityBack to article page
