Chemical and Biological Weathering of Black Shales

A number of black shale elements have a high Clarke concentration: Mo—12.5; U—8.3; V—3.2. Mobile forms of elements washed out of shale during chemical weathering form secondary minerals (gypsum, copiapite, pickeringite and tamarugite), which inherit the geochemical characterization of parent rocks.

Using machine learning to predict selenium and cadmium …

Cadmium (Cd) and selenium (Se) are widely enriched in soil at black shale outcropping areas, with Cd levels exceeding the standard (2.0 mg/kg in 5.5 < pH ≤ 6.5) commonly. The prevention of Cd hazards and the safe development of Se-rich land resources are key issues that need to be urgently addressed.
