| 中文摘要:河南熊耳山沙沟矿床是新探明的一个大型银铅锌矿床。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。这些研究结果不仅有助于了解矿化作用过程，而且为矿床评价、组分综合利用和选 冶提供重要依据。 |

| Abstract:The Shagou ore deposit is a large_size silver_lead_zinc deposit in west Henan Pr ovince. Based on a systematic study of a considerable number of polished ore sec tions as well as ICP_MS and electron microprobe analyses, the authors have found that the main sulfide minerals include galena, iron_poor sphalerite and chalcop yrite, whereas silver minerals are composed chiefly of native silver, pyrargyrit e, argentite, polybasite, and argentiferous freibergite. Associated with sulfide s, these silver_bearing minerals occur in cleavages, fissures or intergranular s pace of galena. The data obtained by the authors are of great significance in un derstanding the ore_forming process, and also provide important information for integrated evaluation of the deposit and for ore dressing and smelting. |
