新疆氯铜矿的发现及其意义

THE DISCOVERY OF ATACAMITE IN XINJIANG AND ITS SITGNIFICANCE

在新疆“三○五”项目的研究工作中，发现了氯铜矿（Atacamite）Cu2（OH）3Cl，其化学成分、粉晶数据、红外吸收光谱、差热分析和物理特征等与标准氯铜矿（智利）基本一致。这是我国首次在自然界发现的氯铜矿。它和本区一系列卤化物的发现，从某种程度上反映了该区成矿环境，表明在该区可以通过原生卤素晕寻找铜矿床和银矿床，具有非常重要的意义。

In our study atacamite [Cu2 (OH)3Cl] was discovered in Xinjiang. The mineral is similar to the standard atacamite with respect to its chemical composition, crystal powder data, differential thermal analysis (DTA), infrared absorption spectral fcatures and physical properties, etc, This is the first discovery of natural atacamite in China. The discovery of this mineral and a series of haloids in western and middle Tianshan, Xinjiang reflects the mineralization environment and provides new clues to searching for Cu deposits and Ag deposits in terms of primary halogen aureoles in those areas.
