摘要： 通过对安阳市第四系各类钻孔的搜集，基本查明了第四系在区内的分布、规模、特征、成因；该区的第四系堆积物，除分布于丘陵地区外，还广布于区内东半部的冲积平原，其岩性岩相变化大，厚度由西向东逐渐变厚，层次由多层到单层，颗粒逐渐变细，成因由冲洪积→冲积→坡冲积的变化规律，同时也反映了由老到新，坡冲积堆积范围由大到小，冲积范围由小到大的演变过程。

Abstract: The distribution, quantities, characteristics and origination of soils of Quaternary Period within Anyang City, Henan Province are studied throughout different bore holes. Except for the rolling hill areas, these materials are widely deposited in the alluvial plains in the eastern part of the City. The geotechnical properties of these materials vary significantly. The thickness of the Quaternary soils increase from west to east. Material deposition varies from multilayers gradually to single layer and the grain size also reduces. The origination of the materials changes from alluvial-fluvial, alluvial and finally to colluvialalluvial. These materials demonstrate an evolution process of from old to new, the area of colluvial-alluvial reduces and the increase of alluvial area.
