摘要
矿床位于临沧帮卖第三纪盆地。矿体主要赋存于N21和N11地层中 ,矿体受褐煤层及碳质层控制 ,呈层状、似层状、透镜状产出。主矿体走向长 4 72m ,倾斜长 4 0 0～ 80 0m ,平均厚4m ,平均品位ω (Ge) =0 0 55% ,可分为锗煤型和锗砂岩型两类矿石。锗主要来源于基底花岗岩。成矿可分为植物富集、沉积富集。
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.
