TL;DR: Time-resolved sample quenching and high-resolution microscopy demonstrate that gypsum forms via a three-stage process, indicating that a stable nanocrystalline precursor phase can form below its bulk solubility and that in the CaSO4 system, the self-assembled nanoparticles plays a crucial role.

Calcium sulfate precipitation pathways in natural and engineered environments
TL;DR: In this paper, a unified model for calcium sulfate crystallization is proposed, integrating both the classical and non-classical perspectives on crystallization, and the phase stability and transformations taking place in the CaSO4-H2O system.

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.

Not just fractal surfaces, but surface fractal aggregates: Derivation of the expression for the structure factor and its applications.
TL;DR: This model of densely packed "brick-in-a-wall" surface fractal aggregates may well be the key precursor step in the formation of several types of mosaic- and meso-crystals.

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).
