10(f) Characteristics of Sedimentary Rocks
Figure 10f-3: Dipping sedimentary layers of rock, Rocky Mountains, Canada. The classification of clastic sedimentary rocks is based on the particle types found in the rock. Some types of clastic sedimentary rocks are composed of weathered rock …
Features that were part of the sediments when they were deposited are often preserved when the sediments become lithified. These features are very useful in rec Bedding. Bedding is often the most obvious feature of a sedimentary rock and consists of lines called bedding planes, which mark the boundaries of different layers of sediment.
What are sedimentary rocks?
Clastic sedimentary rocks are made up of pieces (clasts) of pre-existing rocks. Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped. If the sediment is buried deeply, it becomes compacted and

Sedimentary rocks are formed from material derived from other rocks including plant and animal remains. These rocks thus contain fossils. Sedimentary rocks are generally not crystalline. They are soft and layered as they are formed by deposition of sediments.

· Seven compositional categories, including volcanic quartz, epiclastic quartz (Fig. 4A), sedimentary rock fragments, volcanic rock fragments (Fig. 4E), heavy minerals, and opaques were recognized and used for lithofacies classification.
14 Uses of Sedimentary Rocks in Civil Engineering
Uses of sedimentary rock can be found in almost all buildings and public structures. This makes it substantially important construction material in civil engineering projects. The sedimentary rock is formed by the settlement and subsequent cementation of mineral or organic particles on the floor of oceans or other collections of water. The application of sedimentary rock in civil […]
Oolite is a sedimentary rock made up of ooids (ooliths) that are cemented together. Most oolites are limestones — ooids are made of calcium carbonate (minerals aragonite or calcite ). Ooids are spheroidal grains with a nucleus and mineral cortex accreted around it which increases in sphericity with distance from the nucleus.
Why Fossils are Found in Sedimentary Rock
· Sedimentary rock will not be of a part of a full cycle within the rock cycle if there are to be any fossils available within it. In some rare cases metamorphic rocks may contain some remnants of fossils as these rocks do not undergo a full melting point back to liquid magma.
Limestone is a common type of carbonate sedimentary rock.It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3).Limestone forms when these minerals precipitate out of water containing dissolved calcium. out of water containing dissolved calcium.

Temperature increases can alter the characteristics of the rock as well. If too much heat and pressure occur during diagenesis then the rock may wander into the regime of metamorphism. At times geologist will argue over the boundary between a highly diagenetically altered sedimentary rock and a low grade metamorphic rock.
