It is a rock containing clay and calcium carbonate. It is formed from the erosion of other rocks during weathering; as rocks erode, small sedimentary particles–sand, silt, and clay–pile up on top of each other. Eventually, these sedimentary particles become compacted together to form a new rock.

Most sedimentary rocks contain either quartz (siliciclastic rocks) or calcite (carbonate rocks). In contrast to igneous and metamorphic rocks, a sedimentary rock usually contains very few different major minerals. However, the origin of the minerals in a sedimentary rock is often more complex than in an igneous rock.

Gneiss is a foliated, coarse-grained metamorphic rock with characteristic bands of parallel oriented minerals known as gneissic texture. These bands are easily visible to the naked eye, but lack the schistose tendency to break along the parallel planes. Gneiss is composed of micas (typically biotite), quartz, and feldspar.

29.10.2020Metamorphic rocks are rocks that have changed from one type of rock to another. While sedimentary rock is formed from sediments, and igneous rock is formed from molten magma, metamorphic rock is rock made from pre-existing rocks. These rocks undergo a change, either caused by high heat, high pressure, or exposure to mineral rich hot liquid,

The remaining steps in the formation of sedimentary rocks are transportation, deposition, burial, and lithification (Figure 6.0.2). millions of years separate the weathering and depositional processes, and both types of sedimentary rocks tend to include at least some material derived from both types of weathering.

Shale is one type of sedimentary rock in which fossils are often found. It forms when large rocks disintegrate through erosion into the minute, often microscopic particles transported by wind and rain and deposited into bodies of water.
