Gypsum processing and use
The presence of gypsum on or just below the surface of the ground is often indicated by changes in vegetation; some plants thrive on gypsum-rich (alkaline) soil whereas others are not at all tolerant of those conditions. Gypsum rock is usually white or colourless, although it may sometimes have grey, yellow, pink, or brown hues.
