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.
在形成假蓝宝石的高级变质-深熔作用过程中,岩石矿物组合的变化主要是多阶段变质造成的,如浅-暗色组分发生了分离,其中含镁铁组分多的矿物较早结晶,而镁铁组分的分离使得相对富Fe的矿物较早结晶,即晚期形成的镁铁质矿物更富Mg组分,并形成递进演化的不同阶段的组合。

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.
提出了一种复杂含氧盐矿物的摩尔生成Gibbs自由能和摩尔生成焓的简单估算方法,并把复杂含氧盐矿物分为不含水复杂含氧盐矿物和含水复杂含氧盐矿物,不含水复杂含氧盐矿物可以看作是酸性氧化物和碱性氧化物组成的物质,其摩尔生成Gibbs自由能或摩尔生成焓都可以看作是酸性氧化物和碱性氧化物复合成的化合物摩尔生成Gibbs自由能或摩尔生成焓之和。

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.
