摘要
辽东地区第四系不发育。近年,由于旧石器时期遗迹的发掘,积累了较丰富的古动物、古人类资料,使得我们有可能应用这一成果建立辽东地区中、上更新统的标准剖面。辽东地区中更新统称庙后山组(太子河地区)和牛心山组(丹东—营口区);上更新统称山城子组(太子河地区)和金牛山组(丹东—营口区),代表了0.377—0.017Ma期间的堆积。古生态分析表明,庙后山期(牛心山期)为温暖湿润的森林—疏林草原型自然景观;山城子期(金牛山期)为寒冷的干旱草原—半荒漠型自然景观。
Quaternary System are not developed in eastern Liaonmg. In recent years, after the ruins of Old Stone Age unearthed} the Palaeozoologic and PalaeoanthroPologic data are accumulated so Plentifully that the results can be used lo establish the standard section of Mid and UPP-Pleistocene Series in eastern Liaoning. The Mid-Pleistocene Series is called Miaohoushan Formation in Taizihe area or Niuxinshan Formation in Dandong-Yingkou area; the UPPer-Pleistocene Series is Shanchengzi Formation in Taizihe area or Jinniushan Formation in Dandong-Yingkou area, both of the series are the accumulation during 0. 337-0.017Ma. The analysis of Palaeoecology show that Miaohoushan age (Niuxinshan age) is of warm moist forest-sParse woods grasslands type;Shanchengzi Age (Jinniushan Age) is of cold dry grasslandssemidesert type.
