Sedimentary rocks (layered rocks) are made by the deposition of particles carried in air or water and by the precipitation of chemicals dissolved in water. These particles and chemicals come from the weathering (breaking apart in place) and erosion (carrying away and breaking apart while moving) of rocks on the Earth’s surface.

Composition describes the mineral components found in sediment or sedimentary rock and may be influenced by local geology, like source rock and hydrology. Other than clay, most sediment components are easily determined by visual inspection (see Chapter 3 , Minerals).Sedimentary rocks (layered rocks) are made by the deposition of particles carried in air or water and by the precipitation of chemicals dissolved in water.

Floor 1. Metamorphic rocks form when sedimentary, igneous, or pre-existing metamorphic rocks are changed by heat, pressure, and chemically reactive waters. These rocks are identified by their minerals and texture. During metamorphism, new minerals grow, with different sizes, shapes, and orientations than those of the original minerals.

Lab Activity 6.1 - Categorizing Sedimentary Rocks. First, you will sort rocks by the appearance of their textures, and then you will sort rocks by components that you can see within them. Part B - Sorting Sedimentary Rocks by Composition and Texture. Sedimentary rock composition describes the type (s) of material (s) that make up each rock.The Sr, considering its affinity with Ca, increases its proportion in the marly sediments. The sampled Vaca Muerta rocks have a composition similar to that of the upper continental crust, but with higher contents of V and U. Provenance diagrams and REE patterns suggest that most of the sediments derived from acidic and intermediate igneous rocks.Conglomerate is a clastic sedimentary rock made up of rounded clasts that are greater than two millimeters in diameter. The spaces between the clasts are generally filled with sand- and clay-size particles. The rock is bound together by a cement that is usually composed of calcite or quartz. Sandstone is composed of sand-sized (0.0625…2 mm) mineral grains, rock fragments, or pieces of fossils which are held together by a mineral cement. It grades into siltstone, shale or mudstone (grains less than 0.0625 mm in diameter) and conglomerate (or breccia if the clasts are angular) if the average grain-size exceeds 2 mm 1.
