The simplest sedimentary structure is stratification, which is layering that can be observed in sedimentary rocks (Figure 4.1).Layers of sediment that are thicker than 1 cm are called beds and layers thinner than 1 cm are called laminations.Laminations are typically composed of fine-grained silt and clay-sized sediment. INTRODUCTION 1.1 You might have heard us define structure in rocks as rock geometry on a scale much larger than grains.This is a singularly unilluminating definition, be-cause it doesn't conjure up in the mind of the uninitiated any of the great variety of interesting and significant geometries that get produced by the physical, chemical, – Sedimentary structures preserved on the underside of a bed!

They'll give your presentations a professional, memorable appearance - the kind of sophisticated look that today's audiences expect. (e.g., groove)! LAB 1 Detrital Sedimentary Rocks and Sedimentary Structures In Today’ Lab we will examine the formation and deposition of detrital sedimentary rocks. Sedimentary rock, which makes up most of the surface cover of the continents, is by definition deposited by moving fluids. 4.2 Types of Sedimentary Structures.
