【摘要】：花园铜矿地处新疆乌恰县境内,位于塔里木盆地西缘喀什凹陷。本文通过物相分析对矿石类型进行讨论,利用扫描电镜结合矿相显微镜对氯铜矿、赤铜矿的物理化学特征进行深入研究。研究结果表明:花园砂岩型铜矿氧化程度深,主要矿物为赤铜矿。氯铜矿集合体呈粗糙粒状、胶状和脉状;赤铜矿单晶颜色近于黑色,集合体颜色为紫红色。氯铜矿中Cu的平均质量百分比为55.7%,Cl的平均质量百分比为19.1%,Cu与Cl的质量比近似于3;赤铜矿中Cu的含量为87.7%。笔者认为氯铜矿是在干旱、高气温环境下,孔雀石与含氯离子的水溶液发生反应形成。
[Abstract]:The Huayuan Copper Mine is located in the western margin of the Tarim Basin, Kashi sag. The ore types are discussed by means of physical facies analysis, and the chlorinated copper ores are analyzed by scanning electron microscope (SEM) and metallofacies microscope. The physical and chemical characteristics of hematite are studied in depth. The results show that the oxidation degree of Huayuan sandstone type copper deposit is deep, the main mineral is chalcopyrite, and the collection of chloride-copper deposit is coarse granular, glued and veined; The color of single crystal of hematite is nearly black, and the color of aggregate is purplish red. The average mass percentage of Cu in chloride-copper is 55.7% and the average mass percentage of Cl is 19.1%. The mass ratio of Cu to Cl is approximately 3; The content of Cu in the hematite is 87.7%. The author thinks that the chlorite is formed by the reaction of malachite with the aqueous solution containing chloride ion under the condition of drought and high temperature.
