Fluorite formation

WebJan 15, 2024 · The main driver for its formation is the loss of CO 2 from the water to the hydrocarbon phase (s) as pressure falls. This removes carbonic acid from the water phase, which had kept the basic calcite dissolved. Calcite solubility also decreases with decreasing temperature (at constant CO 2 partial pressure). Webfluorite crystallizing from high-temperature fluids will show a negative Eu anomaly when normalized to REY abundances of the fluid from which it crystallized.

WebFluorite has an isometric formation, meaning the crystals develop symmetrical cubes. Thus, they are found in symmetric chunks although the corners have undergone natural wear. On the other hand, calcite develops as a trigonal hexagonal crystal system due to which many of its specimens look like a double-ended pyramid.
