摘要
本文主要研究兖州矿区第四系松散物的沉积古地形、分析松散沉积物的特征及其沉积环境演化过程。通过对兖州矿区第四系沉积古地形、沉积厚度、沉积物特征等综合分析,得出了第四系沉积厚度变化规律和第四系沉积物岩性在平剖面上变化特点,提出了第四系沉积主要取决于沉积古地形和古河流。
This paper mainly studies the Yanzhou mining area of Quaternary loose deposit of ancient landform,analysis characteristics and sedimentary environment evolution process of loose sediments. Through a comprehensive analysis of the Quaternary sedimentary terrain in Yanzhou mining area,thickness of sediment,sediment characteristics,the characteristics of the Quaternary sedimentary thickness variation and Quaternary sediment lithology changes in the profile,the Quaternary deposition depends mainly on the sedimentary palaeotopography and ancient river.
