Procesy transformujące złoża siarki

Sulfur is stable in a very narrow range of pH and Eh values of deposit water environment. Even minor changes in these values may result in removal of sulfur from one part of the deposit and its precipitation in another place. Such phenomena take place in sulfur deposits, leading to transformation of their original form. The major of these processes include recrystallization of sulfur-bearing limestones, bituminization (involving replacement of sulfur by bitumens occurring in excessive amounts), leaching of sulfur accompanied by origin of cavernous limestones, displacement of sulfur from post-gypsum limestones into the surrounding rocks, kartst and weathering. The process transforming at present the sulfur deposit is that of hot-water sulfur mining.
