What is a type of sedimentary rock.

The type of sediment that is deposited will determine the type of sedimentary rock that can form. Different colors of sedimentary rock are determined by the environment where they are deposited. Red rocks form where oxygen is present. Darker sediments form when the environment is oxygen poor. Sedimentary Rock FormationThere are three types of rocks on Earth, igneous, metamorphic and sedimentary. These are formed in different ways and have different properties.This last group forms sedimentary rocks of largely biological origin. Post-depositional change from sediment to sedimentary rock is called diagenesis, and ...Types of sedimentary rocks based on the mechanisms responsible for their formation: Clastic sedimentary rocks are composed of rock fragments (called clasts) that have been cemented together. Most ...Sedimentary Rock # 2. Breccia: Breccia is a rock composed of angular debris cemented together. These fragments may be produced by volcanic explosion, faulting or sedimentary deposition. The deposited fragments are of similar or different rock types depending on the source area.

The Rock Most Likely to Contain Fossils. Fossils, the preserved remains of animal and plant life, are mostly found embedded in sedimentary rocks.
