Salts from mantle fluids: Hydrothermal anhydrite in the Smokers at mid oceanic ridges

After the previous article defining the physics of evaporation, over the next few articles, I want to discuss ionic salts that are not "true" evaporites. They're not solar-powered, and they're not related to the uptake of solar heat in brine on or near the earth's surface. Instead, they're related to retrograde salt chemistries or the supercritical properties of subsurface brine at extremely high temperatures and pressures. These define some of many situations where ionic salts or saline minerals precipitate and backreact in regions where we do not see brine concentration driven by solar evaporation. So, by definition, these are not "true" evaporites. This is the Chapter 2.1 video from Module 2 - Salts that are not "True evaporites." It's another example of the content from our upcoming online course, "Evaporites; Brines and Sediments. That course will be released in the first quarter of 2025 to become part of our growing catalogue of online courses covering various topics across saline geosystems (https://courses.saltworkconsultants.com/) Chapter 2.1 explores retrograde solubility in and near active mid-oceanic ridges, where black and white smokers occur, with significant volumes of anhydrite. In the following article and video, we'll look at zones of deeply circulating marine brine atop zones of serpentinite formation.
