程潮铁矿矿石微量元素因子分析

鄂东南程潮铁矿矿石微量元素R型因子分析结果表明，在程潮铁矿整个成矿过程中，首先经历了岩浆岩演化期的钠化和钾化阶段。在此阶段中，铁、铜等成矿物质初步富集，并伴随岩浆熔离作用进入到岩浆热液中。在含矿热液演化期又经历了早期的矽卡岩阶段，氧化物成矿阶段和硫化物成矿阶段。热液末期向碳酸盐阶段演化直至矿化作用结束，构成一个完整的岩浆热液成矿过程。

Factor Analysis of Trace Elements of Chengchao Iron Ore

The results of the factor analysis of trace elements in the iron ore of Chengchao Iron Mine in the southeast of Hubei indicates that the ore formation of Chengchao iron deposit experienced the sodium and potassium mineralization in magmatite evolution period, during which, iron and copper were preliminarily enriched as ore-forming substances and entered the magmatic hydrothermal fluid accompanying the magmatic liquidation. In the ore-containing hydrothermal fluid evolution period, it also experienced early skarn stage, oxide mineralization stage and sulfide mineralization stage, and then at the late hydrothermal fluid period, the carbonization stage and the end the mineralization, forming a complete magmatic hydrothermal mineralization process.
