Rock layers names
In Bryce Canyon, there are horizontal layers of sediment. At a fault, part of the rock is displaced, so the horizontal layers are no longer continuous. Some examples at Bryce Canyon include the Bryce Point fault, the Peekaboo fault, and the Fairyland fault. Folds happen when there is a buildup of stress, but the rock bends instead of breaking. The rock names are links. If you click on one, you jump to the description of that rock. ... Does the rock have layers but not crystal grains? (Look carefully for layers, especially along the edges of the rock. You may need a magnifier.) The rock has layers, and crystal grains are not visible. . .

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.When a layered rock is quarried and sawn into blocks, its layers look like stripes. They can be subtle or vivid; straight, wavy, or chaotic. ... The molten rock heats anything nearby, baking it into a metamorphic rock. The geologic name for this is contact metamorphism, because just being near the hotter rock causes the metamorphic effect.
