摘　　要：本文在综述煤中锗矿化国内外研究现状的基础上，以临沧锗矿为例，深入讨论了在煤系地层中形成超大型独立锗矿床的特殊条件。结果表明，煤是锗成矿极有利的围岩，煤能否富集锗主要取决于有无富锗流体与煤相互作用。Based on the data available on germanium mineralization in coal, this paper,as is exemplified by the Lincang germanium deposit,discusses the special conditions for the formation of superlarge germanium deposits in coal seams. The result shows that the coal seams are a kind of country rock extremely favorable to germanium mineralization,and whether the coal is able to enrich in germanium depends principally on whether or not there exists germanium-enriched fluid which can interact with the coal.
