Sulfate crust : ウィキペディア英語版 | Sulfate crust Sulfate crust is a zone observed in the axial (central) parts of burning coal dumps and related sites. It is a zone built mainly by anhydrous sulfate minerals, such as godovikovite and millosevichite. The outer zone can easily be hydrated giving rise to minerals like tschermigite and alunogen. The zone forms due to interaction with hot (even around 600 °C) coal-derived gases (mainly NH3 and SO3) with the "sterile" material (i.e. shales and other rocks serving as the source of Al3+, Fe3+, Ca2+ and other cations) in case of the lack of vents for the gases to escape into the atmosphere.〔Srebrodolskiy B.
