The Dahebian stratiform barite deposit, which is situated in the Nanhua Basin, is one of the world's largest and most important barite deposits. This deposit was formed through sedimentary exhalative processes in the early Cambrian stage.

The order of selectivity of heavy metal accumulation in soils is affected by the pH of the soil. The precipitate is formed at pH values of soil solution above 4 or 5, the selectivity order obtained is Pb > Cu > Zn Cd, as observed for natural clay, illite and montmorillonite soils (Gidlow, 2015, Jusko et al., 2008).
