| 摘 要： | 含氧金矿物在自然界很少产出。经研究，在东坪金矿床中发现了几种含氧金矿物，从成分和物性看可能为新矿物，其化学式为：Ａｕ２（Ｐｂ，Ｆｅ）ＴｅＯ５，Ａｕ２Ｐｂ，（Ｔｅ，Ｓ）Ｏ６，Ａｕ２Ｚｎ（Ｔｅ，Ｐｂ）２Ｏ６，Ａｕ２（Ｚｎ，Ｐｂ）２ＴｅＯ６，Ａｕ２ＣｕＴｅＯ４和Ａｕ２Ｔｅ２Ｏ５。对这些矿物的地质产状和矿物组合，形态及物理性质，光学性质，化学成分作了研究，取得了许多矿物学资料，但Ｘ射线衍射分析结果不理想，

| Abstract: | The formulation of rational grade index for ore deposit is a decisive problem of multiple targets. The mathematical model of the gray sitution decision for formulating rational grade index is set up for solving this problem.By using the method,the rational grade index of some gold deposit in southwest China has been analysed decisively,the results show that this model is feasible. |
