| 摘 要： | 通过对中国广西卡林型金矿的含金毒沙、黄铁矿及用热液实验方法合成的含黄铁矿、白铁矿的分析和研究,特别是光电子能谱分析,发现其中存在电子结合能低于自然金（Ａｕ＾０）的“不可见金”。因而提出金在上述硫化物矿物中由于取代部分硫并与硫呈共价键结合而负价态点。本文料从金的化学及地球化学性质,毒砂,黄铁矿及白铁矿的晶体化学特征和产出的地球化学环境等三方面初步探讨了其形成的可能性。

| Abstract: | In recent years "invisible gold" occurring in sulfide minerals of the Carlin disseminated type gold deposits has attracted wide attention. At present, the most important progress on the study of "invisible gold" comes from the study of Moss-bauer spectra. |

| Keywords: | Carlin-type gold deposit sulfide "invisible gold" chemical bound gold negative charge state of gold |
