| 摘 要： | 矿床位于临沧帮卖第三纪盆地。矿体主要赋存于Ｎ＾２１和Ｎ＾１１地层中，矿体受褐煤层及碳层控制，呈层状、似层状、透镜状产出。主矿体走向长４７２ｍ，倾斜长４００～８００ｍ，平均厚４ｍ，平均品位ω（Ｇｅ）＝０．０５５％，可分为锗煤型和锗砂岩两类矿石。锗主要来源于基底花岗岩，成矿可分为模特富集、沉积富集、成岩富集及后生改造富集四个阶段。

| Abstract: | This ore deposit is located in the Tertiary Bangmai basin in Lincang. The ore bodies are mainly in the N 2 1 and N 1 1 strata, controled by lignite and carbonaceous beds and with bedded, bed like and lens forms. The main ore body is 472m long in strike, 400 800m in dip, with average thickness 4m and average grade w(Ge)=0 055%, consists of Ge coal and Ge sandstone 2 types of ore. The Ge is mostly originated from the basement granite. And the metallogenesis consists of 4 concentration stages, ie, plant, sedimentation, diagenesis and reformation. |
