Magnetites formed by this process constitute the (*) earliest evidence of it, and these magnetites are characterized by being elongated with a single magnetic domain.
Whewellite is created by this process, and is typically found as a thin calcium oxalate pruina patina. Minerals created by this process are often mosaiced or mesocrystalline, owing to an enforced heterogeneous crystallization environment. Celestite deposits found near hydrothermal vents are typically formed by this process. Magnetites formed by this process constitute the (*) earliest evidence of it, and these magnetites are characterized by being elongated with a single magnetic domain. When vaterite is formed by one particular case of this process, it is stabilized and has a spherical morphology, owing to unidentified catalysts in nacre. Apatite formed by this process is typically hydroxyl-substituted. It is not known to have occurred macroscopically during the Precambrian. For 10 points, name this process that is used by molluscs to make their calcite shells.
