Vanadium mainly exists as independent minerals or in clay minerals in the form of isomorphism, with a small amount absorbed by clay minerals and limonite. Nickel mainly exists as independent minerals. Molybdenum occurs as colloidal sulfides with carbon, sulfur and clay, and forms molybdenite through thermal metamorphism. Uranium is unevenly scattered in collophanite and carbonaceous_argillaceous materials in the form of isomorphism or adsorption. REE mainly occur in collophanite in the form of isomorphism. Copper, lead and zinc chiefly exist in sulfides or sulfo_arsenides and are concentrated in the metallic layer.
