本文根据大量的野外地质钻探、水文地质试验、岩性调查等资料 ,从区域地下水形成的地质条件入手进行分析。查明了通辽地区第四纪地质实体各期岩相古地理、沉积构造特征、地层空间结构、沉积物粒度的空间变异 ,据此进行了地层分区。为通辽地区含水层系统的分析与辨识 ,研究垂向水交替 ,准确测定有关参数提供可靠的地质依据。并据此进行了地质分区
Based on a large number of field geological drilling, hydrogeological test, lithological survey and other data, this article analyzes the geological conditions of the formation of regional groundwater. The stratigraphic zonation of the Quaternary geological bodies in Tongliao area was identified, including lithofacies palaeogeography, sedimentary structural characteristics, stratigraphic spatial structure and sediment grain size. It provides a reliable geological basis for the analysis and identification of aquifer systems in Tongliao area, study of vertical water alternation, and accurate determination of relevant parameters. And according to the geological division
