对中国河北东坪金 -碲化物型金矿的成分及性质复杂多样的金矿物的研究表明 ,东坪金矿产有由不同尺寸微粒金与碲酸盐 /亚碲酸盐 /含水氧化物组成的一些特殊的混合相 ,具芥末状或胶状结构 ,沿用“芥末金”之称。研究所获众多的分析数据得以对这些成分复杂的物质进行鉴别和分类。并按碲金矿蚀变模式 ,利用孔隙中充填的针铁矿、水硫碲铅石、绿碲铁矿、黄碲矿、黄碲铁石、碲酸等 (或一些未知混合相 )对铁芥末金、碲铅芥末金、碲铁芥末金、锰铅芥末金等各类型的化学组成及性质进行模式化。与前人资料进行了对比 ,对蔡长金、田澍章等描述过的金的碲酸盐或氧化物矿物做出了新的解释 ,提出其中某些未定名的新矿物应解释为芥末金的变种。根据电子能谱学数据推测 ,芥末金中可能存在金的纳米级团簇。
The study on the composition and properties of the gold deposits of the Dongping gold-telluride type in Hebei, China, shows that the gold deposits in the Dongping gold deposit are composed of fine-grained gold and tellurite / tellurite / hydrous oxides Some special mixed phase, with mustard or gel-like structure, follow the “mustard gold”. The numerous analytical data available to the Institute allow the identification and classification of these complex components. And according to tellurium gold alteration mode, the use of goethite, water sulfur tellurium feldspar, green tellurite, tellurite, tellurite, telluric acid (or some unknown mixed phase) filled in the pores of iron mustard Gold, tellurium and lead mustard gold, iron telluride and gold, manganese and lead mustard gold and other types of chemical composition and properties of the pattern. In contrast with previous data, a new interpretation of gold tellurites or oxide minerals described by Cai Changjin, Tian Shuzhang et al. Suggests that some of these new unnamed minerals should be interpreted as variants of mustard gold . According to the data of electron spectroscopy, it is speculated that gold nano-scale clusters may exist in mustard gold.
