摘要
辽宁抚顺东部地区处于长白山脉南延的龙岗山系中,由玄武岩组成的火山台地和大面积冰水堆积物构成的夷平面,共同组成了抚顺东部地区第四纪特殊的地貌景观,依据1/5万区调成果,对抚顺东部地区第四纪地层进行了划分和对比研究,把更新统由下至上划分了8个自然单元,全新统由下至上划分了3个自然单元。提出了抚顺地区更新世由早期至晚期至少存在三期冰水堆积物的新认识。
East Fushun Area is located in Longgang Mountains of southern extension of Changbai Mountain. The basaltic volcanic platform and the plantation surtSce built by large area of water deposits, formed the special quaternary geomorphologic landscape of East Fushun. Based on the data of 1:50000 geological survey, this article tries to make a preliminary division and comparison to the quaternary strata in East Fushun. The Pleistocene stratum is classified into 8 natural units from the bottom to tile top and the Holocene stratum is classified into 3 natural units from the bottom to the top. New knowledges have been proposed in this article that there exist at least three period of outwash sediments in early-late Pleistocene stratmn in Fushun area.
