【摘要】 对川西北哲波山微细浸染型金矿床金的赋存状态进行了研究 ,结果表明金在原生矿内主要载金矿物毒砂和黄铁矿中是以显微、超显微的包裹金形式存在 ,在氧化矿石中是以游离金的形式存在。晶格金的可能性较小。主要载金矿物黄铁矿的生长环带中金的含量边缘比核部高 ,亮带比暗带高。并结合黄铁矿中微量元素的分布特征 ,认为金沉淀的环境是总体较稳定、局部振荡的环境更多还原

【Abstract】 In this paper,the existent states of gold in Zhebo micro disseminated gold deposit,north western Sichuan is expounded.The gold occurs in the form of micro ultramicro inclusions in pyrite and arsenopyrite that are major host minerals for gold in primary ore boby.The content of gold in outer zones and bright belt of zonal pyrite are higher.From distributive feature of the trace elements in pyrite we can draw a conclusion that the gold depositing environment is stable in general but variable in part.更多还原
