Abstract

Chemical and structural data of two Cu-rich coloradoite crystals from Kalgoorlie, Australia, are reported. Two grains with simple stoichiometries, i.e., Hg_1 – xCu_xTe with x ~0.30, and ~0.22, were characterized by single-crystal X-ray diffraction and electron-probe microanalysis. In the absence of single-crystal data it might be tempting to hypothesize that the presence of large amounts of other elements can induce some ordering leading to distinct mineral species. However, structural analyses show that all of the phases are cubic and crystallize in the space group \(F\overline 4 3m\). On the basis of information gained from the chemical and structural characterization it can be concluded that there is a complete solid solution between coloradoite and a possible, still unknown, Cu-coloradoite in nature.

科罗拉多州HgTe中的铜：实际状态还是分析伪像？

摘要

据报道，来自澳大利亚卡尔古利的两种富含铜的科罗拉多辉石晶体的化学和结构数据。通过单晶X射线衍射和电子探针显微分析表征了具有简单化学计量的两种晶粒，即Hg _{1 –  x} Cu _x Te，x分别为〜0.30和〜0.22。在没有单晶数据的情况下，可能会试图假设大量其他元素的存在会引起某种排序，从而导致不同的矿物种类。但是，结构分析表明，所有相均为立方晶且在空间群\（F \ overline 4 3m \）中结晶。。根据从化学和结构表征中获得的信息，可以得出结论，在科罗拉多岩与自然界中一种可能的，仍未知的Cu-科罗拉多岩之间存在完整的固溶体。
