摘　　要：临沧邦卖盆地演化经历了成盆期、静默期、扩张超覆期三个主要时期,区内锗煤矿是花岗岩风化淋滤微细粒和含锗流体在泥炭沼泽内,植物遗体煤变过程中吸附络合富集成矿,同沉积张拉裂隙、热液作用等,对后期改造成矿有促进作用,但热液作用并非必要成矿因素。The Bangmai Basin in Lincang has experienced three main periods:basin formation period,quiet period and extended overlap period.The germanium coal deposits in the area were formed by adsorption,complexation,and enrichment of fine particles and germanium containing fluids,which were leached from weathered granite and stored in peat swamps,during the coalification process of plant remains.The synsedimentary tensile fissures and hydrothermal processes could promote the late metallogenic transformation,but hydrothermal processes are not necessary factors for mineralization.
