| 摘 要： | 吉林省东南部早寒武世晚期地层中含有数层含铜层，它们主要赋存在红色岩层所夹的灰绿黄绿色岩层之中。本区含铜层的形成与当时富氧阶段中的缺氧时期息息相关；而且该类型含铜层主要产自滨海或滨浅海地带，受当时古地理严格控制

| Abstract: | There are some sedimentary copper-mine beds in the late period of the Lower Cambrian of the Southeastern Jilin Province. They are formed by precipitation and bioprecipitation. Mine rocks are mainly contained in the grey green of yellow green beds which are intercalated in the red rocks that formed in the conditions of the hot dry and rich oxygen. The author consider the precipitated copper as the result of anoxic sedimentary environment. These mine rocks are formed near the shore shallow marine zone. They are strictly dominated by the palaeogeography of the later period of the Early Cambrian. |
