摘要
本文主要对豫北安阳岳城水库一带的泥砾沉积物进行了描述,并将其与在重新编制"河南省1:50万第四纪地质图"时广泛收集的以往河南省泥河湾期的地质资料进行对比、分析,认为这套泥砾沉积物为一套第四纪泥河湾期晚期的冰碛物,确定其绝对地质年龄为97万年。
This paper mainly describes mud-graval sediment in Yuecheng reservoir region,Anyang of nouthern Henan in period Nihewang,and contrasts with previous formation about nihewan period ＂Henan 1：500,000 quaternary geological map of Henan province＂,considers this sediments is a Nihewan period＇s glacial sediment and its absolute age is 970,000 years.
