What type of rock is lystone and sandstone?
There is no such ting as "lystone" Sandstone is a sedimentary rock. Limestone is a sedimentary rock of organic origin.
What are rock sediments?
There are organic rocks, like Limestone, and clastic (composed of fragments), like Sandstone. Within these groups there are others, like coal is organic and siltstone is clastic, but even within limestone and sandstone, there are further categories. There's oolitic limestone, chalk and 'shelly' limestones; and arkose, desert sandstone, orthoquartzite (generic sandstone), and others. Conglomerate is an interesting one, if you are after a rock that is not 'normal'.
What is an organic biogenic sedimentary rock - basalt coal sandstone or conglomerate?
Basalt is an organic biogenic sedimentary rock that forms from the cooling of magma. It is not coal, sandstone, or conglomerate, which are sedimentary rocks formed from the accumulation and cementation of organic debris, sand particles, and mixed rock fragments respectively.
What kinds of stone are canyons made of?
Sedimentary, mainly versions of sandstone and limestone, both chemical and/or organic.
What happens if sandstone is heated?
When sandstone is heated, the minerals within it may undergo chemical changes and can potentially recrystallize, altering its physical properties. This can result in the release of water and organic matter within the sandstone, leading to changes in its color, texture, and strength. In extreme cases, excessive heating can cause the sandstone to fracture or break apart.
What type of sedimentary rock is sandstone?
Sandstone is a type of sedimentary rock that is composed of sand-sized grains of minerals, rock, or organic material. It is typically formed in environments where sand accumulates and is compacted over time, such as beaches, rivers, or deserts.
What is the streak of sandstone?
Rocks are not considered to have a streak, as they may consist of several minerals. In the case of sandstone, the rock could be composed of feldspar, quartz, glauconite, and other minerals. Minerals in solutions can penetrate and stain the sandstone as well and affect the attempted streak test.
How would you classify coal coral reef salt sandstone and conglomerate?
Coal and coral reef limestone are organic sediments salt is an evaporite Sandstone and conglomerate are sedimentary deposit rocks the latter from a high energy environment. They are ALL sedimentary deposits.
What is the streak of sandstone and the hardness?
Streak and Mohs hardness are descriptive and identifying terms for minerals. Because sandstone could be composed of a multitude of different rock particles or minerals, a specific hardness or streak cannot be attributed to them.
Four examples of sedimenatary rocks are?
Sandstone, limestone, shale, and conglomerate are examples of sedimentary rocks. Sandstone is formed from compacted sand grains, limestone is made from organic remains like shells or coral, shale is composed of fine clay particles, and conglomerate consists of rounded pebbles cemented together.
What are examples of organic sedimentary rock?
Examples of organic sedimentary rocks include coal, which forms from the accumulation and compaction of plant remains, and limestone, which can contain organic debris such as shells and coral. Organic sedimentary rocks are derived from the remains of living organisms.
What is a kind of organic sedimentary rock formed from the decayed remains of plants a sandstone b limestone c shale or d coal?
Coal is the only option being a solely organic product. Sandstone, Limestone and Shales may contain considerable amounts of coalified organic matter of marine or continental origin (up to several per cent) but the larger fraction of material is detrital slicates in the case of sandstones and shales and carbonates in the case of a limestone.
