【摘要】 老柞山金矿床中的毒砂是主要载金矿物之一 ,结晶程度较好。单形主要为n{ 1 0 1 }、u{ 1 2 0 }、q{ 2 1 0 }、f{ 1 40 }、t{ 2 3 0 }、e{ 0 1 2 }等 ,聚形多为菱形扁柱状。不同世代、不同形态、不同粒度的毒砂含金性差异明显 ,中细粒、半自形 -自形的毒砂可作为该矿区寻找富矿的形态标型。更多还原

【Abstract】 Arsenopyrite is an important gold bearing mineral in Laozuoshan gold deposit,of which the crystal form is better and simpler The main crystal forms are rhombus flattened column formed by n{101}、u{120}、q{210}、f{140}、t{20}、e{012} etc with the different stages,morphology and granularity of the arsenopyrite,the auriferous character of them are quite different.The smaller the crystal grain and the better the crystal forms,the better the aucriferious charater of arsenopyrite The crystal morphological typomorphism of arsenopyrite has been established.更多还原
