In the high-grade metamorphism and anatexis process, in which sapphirine was formed, the multistage crystallization of minerals resulted in the complexity of the mineral association, such as the differentiation of leuco-and melano-components. Generally, the mafic-rich minerals formed earlier, and the differentiation of magnesio-and iron-components is responsible for the earlier presence of ironrich minerals, i.e., magnesio-rich minerals crystallized later, thus the successive associations of multistage occurred.

A simple estimation method for molar Gibbs free energy and enthalpy of formation for complex oxysalt minerals is proposed. Complex oxysalt minerals are divided into complex oxysalt minerals with water and complex oxysalt minerals without water. Complex oxysalt minerals without water can be considered as the composite of acidic oxides and alkaline oxides, so their molar Gibbs free energy or molar enthalpy of formation can be calculated by the summation of molar Gibbs free energy or molar enthalpy of formation of the acidic oxides and alkaline oxides which are combined into the complex compounds.

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.

We report here on the characterization of copper-plated screen-printed electrodes modified by different clay minerals for the same purpose. The results indicated that clay minerals could improve oxidative and reductive currents of copper through the adsorption of copper ion on the surface of clay minerals. Nontronite showed the largest improvement in reductive currents of copper among the three clay minerals studied.
