TL;DR: Using truly in situ and fast time-resolved small-angle X-ray scattering, this work quantifies the four-stage solution-based nucleation and growth of gypsum (CaSO4·2H2O), an important mineral phase on Earth and Mars, and allows for a quantitative understanding of how natural calcium sulfate deposits may form on Earth.
The gypsum–anhydrite paradox revisited
TL;DR: In this article, the authors show that intrinsic thermodynamic and kinetic properties severely constrain the precipitation of anhydrite (compared to gypsum and bassanite), and consequently, a considerable amount of time (e.g. > 2 years at 60°C) is needed for anhydite to form.

TL;DR: In this article, the role of supersaturation, temperature and additives (Mg2+ and citric acid) on the precipitation mechanism and rate of gypsum was investigated in a Synchrotron-based small-and wide-angle X-ray scattering (SAXS/WAXS) setup.

Unraveling the Sulfate Sources of (Giant) Gypsum Crystals Using Gypsum Isotope Fractionation Factors
TL;DR: In this paper, the authors combine newly determined isotope fractionation factors of gypsum precipitated in the laboratory with the isotopic compositions of natural anhydrite and Gypsum to unravel the sulfate sources of the giant selenite crystals in the Naica mine (Chihuahua, Mexico).
