The black shale series in the Qinling Mountains are made up of carbonaceous argillite, carbonaceous siliceous argillite, silicalite, argillite, marlstone, stone coal and carbonaceous limestone. Phosphatic nodules, pyrite and barite are always found in these rocks. Geological and geochemical study shows that the black shale series formed by hydrothermal fluids and biological action in an anoxic environment. The complex metallogenic matter had multiple sources.
