摘　　要：西藏班公湖 -怒江成矿带的典型样品中价态金的分析结果显示土壤 (残坡积物 )中Au0 和Au3+显著相关 ,相关系数 ( γ)为 0 .96;水系沉积物中∑Au和Au3 + +Au+ 具相关性 ,相关系数 (γ)为 0 .50。以此为例探讨了高原湖沼区价态金分布的成因。This paper presents the resultant of valent form trace gold by the typical examples from the middle part of the Bangonghu Lake to Nujiang River mineralization belt,Tibet.The expermental fact indicates that Au 3+ and Au 0 are closely related in the soils samples,the correlation coefficient (r) is 0.96, ∑Au and (Au 3++Au +) are correlative in the stream sediments samples,r=0.50.For example above ,the source and gensis of Au 0 ,Au 3+ and Au +,and its significance of oreprospecting have been discussed.
