是否存在Au2Te的新矿物相?
Whether Au2Te is a new mineral phase or not?
"Au2Te"一直作为一个未知矿物或可能的新矿物被多次报道,但缺乏系统的矿物学参数。2011年以来,作者在研究黑龙江三道湾子金矿床物质组成时也发现了"Au2Te"。通过反光显微镜下观察、电子探针与元素面扫描分析,也曾认为其是一具有成分分布均一的未知矿物。然而,作者进一步采用高倍扫描电镜背散射图像、微区XRD分析及数值化图像模拟表明,在微米尺度下成分均一的"Au2Te"不是一个新矿物相,而是一个具有纳米级文象结构由自然金和碲金矿组成的混合物,其构成的图像完全可以与图灵斑图相类比。
u2Te has been reported previously as a new unnamed mineral or a new mineral, although lacking adequate mineralogical data. Since 2011, ore examination utilizing optical microscope, EPMA, SEM backscatter and X-ray images from the Sandaowanzi gold deposit, China, has revealed that "Au2Te" grains appeared to have a homogeneous composition and might be a new unnamed mineral. However, the high resolution SEM, micro-zone XRD and the digitalized image analyses demonstrate that the "Au2Te" phase is essentially not a new mineral species but a mixture of native gold and calaverite with a nanographic texture that is highly comparable to that of the Turing pattern.
