The word ‘sediment’ comes from the Latin words sedimentum, meaning settling, or sedēre, to sit or sink down.. The processes of weathering and erosion gradually break up rocks into sediments. After sediments are deposited, they can become buried underneath layers of ‘fresh’ sediments.Over long periods of time, layers of sediments …4.2 Types of Sedimentary Structures. 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.

Geologists have assigned names to these individual rock layers. The names are from places where the rocks are or were at one time well exposed. For example, the Jordan Sandstone is named for the city of Jordan, Minnesota; and the St. Peter Sandstone, for the St. Peter (now Minnesota) River near Fort Snelling State Park.
