'''层理'''是岩石沿垂直方向变化所产生的层状构造。它通过岩石的[[物质]]成分、结构和颜色的突变或渐变显现，是沉积岩和某些火山碎屑岩的重要成因标志。沉积岩中的层理通常是沉积过程中沉积环境或沉积作用变化的标志，在所形成的层理面上下发生了不同程度的差异，导致岩石中形成明显的[[层理]]。具有层理被看作是沉积岩的一个重要的特征。<ref>[https://www.360kuai.com/pc/9e93de2b86d7b44a2?cota=3&kuai_so=1&sign=360_57c3bbd1&refer_scene=so_1 岩石的层理结构发育的特别完整典型 ],快资讯 , 2020-03-23</ref>
