云南临沧锗矿床褐煤和硅酸盐微量元素地球化学研究表明，大部分微量元素主要来自沉积盆地基底的白云母花岗岩，锗主要由热液携带，富Ge褐煤中Ge与Nb呈正相关，Nb可作为锗成矿的指示元素。所有结果均来自51个富矿物煤样、5个无矿物煤样和9个硅酸盐煤样。
Trace element geochemistry studies of lignites and silicates in Lincang germanium deposit,Yunnan Province indicate most trace element mainly came from the muscovite granites in the basement of the sedimentary basin,germanium was mainly carried by hydrothermal water,a positive correlation was found between Ge and Nb in the Ge rich lignites,Nb can be regarded as the indicate element of germanium mineralization.All results came from 51 mineral rich coal samples,5 mineral free coal samples and 9 silicate samples with ICP MS method.
