Polymetallic black shales are complex resources, which could show enrichment in the number of heavy and rare metals, including vanadium. In black shales, enriched metals dominantly occur via disseminated sulfidic minerals or via different organic-metal complexes.

The natural acid neutralisation potential varies depending on the adjacent rock ...
It has been generally accepted that black shales are oil shales and have to be handled as sources of fuel oil. This attitude has been so prevalent that it is applied even to those thermally mature black shales in Jamtland (Sweden) and Sillamae (Estonia) that supply practically no oil on thermal treatments even in the presence of hydrogen. It may well be that these shales are a very significant ...
