 GyPSuM is a 3-D model of mantle shear wave (S) speeds, compressional wave (P) speeds, and density.The model is developed through simultaneous inversion of seismic body wave travel times (P and S) and geodynamic observations while using realistic mineral physics parameters linking wave speeds and density.Geodynamic observations include the global free air gravity …
Preliminary examinations in gypsum plants in Germany revealed that the current state of the art procedure to determine the gypsum content in processing plants are offline laboratory analyses. They provide highly precise information for the process, but do not offer the possibility of online monitoring for quality control because of time delay.
Synchrotron-based small- and wide-angle X-ray scattering (SAXS/WAXS) was used to examine in situ the precipitation of gypsum (CaSO4·2H2O) from solution. We determined the role of (I) supersaturation, (II) temperature and (III) additives (Mg2+ and citric acid) on the precipitation mechanism and rate of gypsum. Detailed analysis of the SAXS data showed that for all tested …
