In this HOT Article, Franca Jones suggests the existence of highly disordered clusters that form prior to crystallization of barite and gypsum, based on Fourier-Transform infra-red (FTIR) spectra of saturated solutions as they crystallize. Jones reports the evolution of various mineral phases prior to the appearance of the crystalline mature product and in the case of barite, shows that the FTIR evidence is strongly supported by electron diffraction. The role of water in the process is also investigated… |
