How does clastic sedimentary rock differ from chemical sedimentary rock quizlet?

How does clastic sedimentary rock differ from chemical sedimentary rock quizlet?

Clastic sedimentary rock forms when fragments of preexisting rocks are compacted or cemented together. Organic sedimentary rock forms from the remains of plants or animals. Chemical sedimentary rock forms when minerals precipitate from a solution or settle from a suspension.

What is the difference between chemical and clastic sedimentary rocks name an example of each?

Clastic sedimentary rocks form from the accumulation and lithification of mechanical weathering debris. Chemical sedimentary rocks form when dissolved materials preciptate from solution. Examples include: chert, some dolomites, flint, iron ore, limestones, and rock salt.

What is the difference between organic and inorganic sedimentary rock?

If the sediment in a sedimentary rock is made of organic materials, it is called an organic sedimentary rock. If the material comprising the rock is inorganic, it is called an inorganic sedimentary rock. Example is sandstone which is made of materials like quartz and feldspar.

What is the difference between fine grained and coarse grained igneous rock?

Coarse grain varieties (with mineral grains large enough to see without a magnifying glass) are called phaneritic. Granite and gabbro are examples of phaneritic igneous rocks. Fine grained rocks, where the individual grains are too small to see, are called aphanitic. Basalt is an example.

How can you distinguish between a sedimentary rock and a foliated metamorphic rock if both have observable layering?

Foliation is developed by stress and fire while layering is developed by the embedding of fine and coarse deposits. Foliation is caused due to an alteration of minerals from pressure and heat while layering is developed by seasonal changes. Foliation has layers while layering contains marks on them.

What is the difference between clastic and crystalline rocks?

Clastic texture: grains or clasts do not interlock but rather are piled together and cemented. Crystalline texture: Crystals are visible and form an interlocking network. Unlike igneous crystalline textures, however, sedimentary crystalline textures are typically formed from one mineral throughout the entire rock.

What are organic sediments?

Organic sedimentary rocks are those containing large quantities of organic molecules. Organic molecules contain carbon, but in this context we are referring specifically to molecules with carbon-hydrogen bonds, such as materials from the soft tissues of plants and animals. An important organic sedimentary rock is coal.

What is non-clastic sedimentary rock?

Non-clastic textures are found chiefly in rocks that have precipitated chemically from water (chemical sedimentary rocks), such as limestone, dolomite and chert. Other non-clastic sedimentary rocks include those formed by organisms (biochemical rocks), and those formed from organic material, such as coal.

What is the difference between chemical and clastic sediments?

Clastic sedimentary layers are formed by erosion and the accumulation of small broken bits of rock. Chemical sedimentary layers and organic sedimentary layers are not the result of erosion. Chemical sedimentary layers are the accumulation of precipitates of organic material.

What characteristics separate clastic chemical and bio clastic sedimentary rocks?

Sediments are squeezed together by the weight of overlying sediments on top of them. This is called compaction. Cemented, non-organic sediments become clastic rocks. If organic material is included, they are bioclastic rocks.

What type of rocks are silicicic and clastic?

Mainly silicic rocks like sandstone, shale etc. fall under clastic rocks. Organic sedimentary rocks: Sedimentary rocks which are formed due to biogenic activity/processes or form from organic matter are called organic sedimentary rocks. Coal is a classic example of organic sedimentary rock.

What is the difference between clastic and chemical sedimentary layers?

Clastic sedimentary layers are formed by erosion and the accumulation of small broken bits of rock. Chemical sedimentary layers and organic sedimentary layers are not the result of erosion. Chemical sedimentary layers are the accumulation of precipitates of organic material.

What determines the type of sedimentary rock that is formed?

The size of the clastic material determines the type of sedimentary rock that is formed. Organic sedimentary layers may not be caused by erosion at all. Coal which is an example of a sedimentary material is formed when organic material like plants are buried between other sedimentary layers.

What are biogenic sedimentary rocks?

Biogenic sedimentary rocks are rocks created from organisms. Organic contents can include animal skeletal fragments and remains, plants, and ocean life remains such as corals, molluscs, radiolarian, and diatoms. Sometimes called organic sedimentary rocks, these organic elements collect in layers and are cemented together by pressure.
