Based on a systematic study of a considerable number of polished ore sections as well as ICP-MS and electron microprobe analyses, the authors have found that the main sulfide minerals include galena, iron-poor sphalerite and chalcopyrite, whereas silver minerals are composed chiefly of native silver, pyrargyrite, argentite, polybasite, and argentiferous freibergite.

文章首次对其矿石矿物进行了系统的研究，通过对大量矿石光薄片观察、等离子质谱和电子探针分析，表明具有工业意义的硫化物主要有方铅矿、贫铁闪锌矿、黄铜矿，银矿物主要有自然银、深红银矿、辉银矿、硫锑铜银矿、含银黝铜矿，它们与硫化物共生，多沿方铅矿、贫铁闪锌矿等颗粒间或者裂隙产出。

The HEED, XRD, and XPS results confirmed the forming of intermetallic compounds between silver and rare earth. As far as silver and lanthanum be concerned, the format of intermetallic compound is AgLa.

由此，本文首次提出了稀土元素在稀土金属间化合物中的能量传递模型，认为稀土与银金属间化合物的4f能级位于费米能级附近下方，部分局域化且与导带部分耦合。4f能级与导带能级之间的电子跃迁是稀土元素在Ag-BaO薄膜中传递能量的方式，也是光电发射增强效应的来源，而4f电子的光吸收截面随入射光子能量的增加而增大的特点则是"蓝强"现象的原因。
