摘　　要：运用多种近代测试手段,查明了金牙金矿床主要戴金矿物毒砂、黄铁矿、粘土矿物中金的三种赋存状态。呈显微—超显微粒状形式的金各占毒砂和黄铁矿中金的90.6%和96.9%,固溶体金分别为9.4%和3.1%。被粘土矿物吸附的胶体金占矿石金的4.81%。对显微—超显微金粒的形态、粒度及数量比进行了某些定量测算。Three existent states of gold among the main gold-bearing minerals-arsenopyrite, pyrite andclay minerals at the Jinya gold deposits have been found with application of various modern detectionmeans. The arsenopyrite and pyrite have 90.6 percent and 96.9 percent in content, respectively, of thetotal gold that exist in the form of micrograins-ultramicrograins while there are 9.4 percent and 3.1percent of gold existing as solid solution in those two minerals, respctively. The colloidal gold absorbedby clay minerals takes up 4.8 percent of ore gold. The shape, grain size and content ratio of the micro-granular-ultramicrogtanular gold are quantitatively checked and calculated.
