笔者2012年在班戈西1/5万区域地质调查工作中，依据桑日PM5号剖面中岩石组合特征及笔石化石将原德吾卡下组划分为上下二段。下段主要为笔石粉砂岩相。上段主要为中层生物碎屑粉晶灰岩与灰绿、黄绿、黄褐色薄层粉砂岩互层。在下段笔石粉砂岩层位中获得的笔石化石，经鉴定种属为Monograptus sp，时代为早志留世。
필자2012년재반과서1/5만구역지질조사공작중，의거상일PM5호부면중암석조합특정급필석화석장원덕오잡하조화분위상하이단。하단주요위필석분사암상。상단주요위중층생물쇄설분정회암여회록、황록、황갈색박층분사암호층。재하단필석분사암층위중획득적필석화석，경감정충속위Monograptus sp，시대위조지류세。
In 2012, the author worked in Bangor West 1:50 000 regional geological survey, based on the rock combination features and graptolite fossils in the Sangri Proifle PM5, divided original Dewuka lower Group into two sections. The hypomere is mainly graptolite silt sand facies. The upper is mainly middle bioclastic powder crystal limestone and celadon, olivine, tawny thin siltstone interbedded. The lower is mainly graptolite silt lithofacies. The graptolite fossils which obtained from lower graptolite siltstone layers, was identiifed species of Monograptus sp, Early Silurian.
