沉积岩的构造是沉积岩的一个很重要的特征。层理、波痕、干裂、雨痕、冲刷痕迹、虫迹和其它生物活动的印痕、结核、变形构造等均为这方面的研究内容。这些特征同沉积岩的物质成分、颜色、结构、岩层之间的接触关系等一样,是追溯沉积岩生成存在条件与发展情况的实际依据。层理: 绝大部分沉积岩具有层理。层理是沉积岩物质在垂直方向上的变化,以其成分、粒度、颜色等方面的差别表现出来。层理的最小单位叫层纹,其厚度以毫米或厘米计算,由成分、厚度和产状相似的同类型的层纹构成层系,若干相似的层系组成了层系组。纹层彼此平行者为水平层理;
The structure of sedimentary rocks is a very important feature of sedimentary rocks. Layer, wave marks, dry crack, rain marks, erosion marks, traces of insects and other biological activities, tuberculosis, deformation structure are the research content in this area. These characteristics are the same as those of sedimentary rocks, such as material composition, color, structure and contact between rock formations, and are the actual evidences for tracing the existing conditions and development of sedimentary rocks. Lining: Most sedimentary rocks have bedding. Layer is the change of sedimentary rocks in the vertical direction, with its composition, particle size, color and other aspects of the difference shown. Layers of the smallest unit called layer pattern, its thickness in millimeters or centimeters, composed of the same type of composition, thickness and appearance similar to the formation of strata, a number of similar strata formed layer system. Layers parallel to each other for horizontal bedding;
