摘　　要：通过对岩石类型、矿石成分及古地理、古气候、古地球化学环境的初步分析认为,区内矿床形成于交替的氧化—还原环境的还原条件下,是受青山口组中、上部层位控制的内陆湖泊相沉积的层控沉积矿床。Through the analysis of petrographic classification, ore composition, paleogeography, paleoelimate, paleogeoehemieal baekground, it is eonsidered that the deposit in the study area was formed in reduction condition from alternate reduction-- oxidation, whieh belongs to inland lake stratabound sedimentary mineral deposit controlled by the middle, upper strata of the Qingshankou Formation.
