Sedimentary Rock

Coal is formed from the remains of plant material that has been partially decomposed and subjected to high pressure and temperature over millions of years. This gives coal its unique characteristics of being a combustible rock that is rich in carbon. Other sedimentary rocks, such as sandstone or limestone, are typically formed from the accumulation and cementation of mineral or organic particles without undergoing the same transformation process as coal.

Sedimentary rocks break down due to weathering processes such as erosion, mechanical weathering (like freezing/thawing), chemical weathering (like water and acids), and biological weathering (from plants/animals). These processes weaken the rock structure and can eventually lead to the breakdown of sedimentary rocks into smaller particles.

The lower coraline limestone is the oldest because it was deposited first in the geological sequence. This means that it was formed or deposited before the upper layers of limestone, making it the eldest layer in that particular sequence of rock formations.

I think it is, "The settled rock", but I'm not sure. Well I am, kinda. Whatever.

The thickest sedimentary deposits are typically found in sedimentary basins, such as rift valleys, continental shelves, and deep-sea trenches. These areas accumulate sediments over millions of years due to processes like erosion, deposition, and tectonic activity. The thickness of the deposits can range from a few kilometers to tens of kilometers deep.

Dolomite can be found in sedimentary rocks like limestone and marble, as well as in hydrothermal veins. It can also form in shallow marine environments from the accumulation of calcium and magnesium-rich debris. Additionally, dolomite can be produced synthetically for various industrial purposes.

Extrusive rocks are... extruded... onto the surface as the lava that we all think of. It cools fairly quickly, into rocks with fairly small crystals (might need a magnifying lens to see them). The exact chemistry of the parent magma will determine the type of rock. Oceanic volcanoes are generally basaltic (mafic or ultramafic), continental are generally granitic (felsic or intermediate). They're put down in "relatively thin" layers

Intrusive rocks cool for thousands of years beneath the surface in huge plutons or batholyths. This allows them to grow very large crystals (easily seen by the unaided eye). These intrusive rocks are almost always granitic-type rock.

you find limestone in Bottswana, Guinesy, Belgium, Switzerland, Australia and the best place Broadesabentland limestone was first found in Newfoundland eg Broadesabentland By Geologist Davidenko Broadyalobentla from Italy in 1890.

Yes, limestone can have layers or bands, which are often formed due to variations in sediment composition and environmental conditions during the deposition process. These layers are referred to as bedding planes and can be visible in the rock as distinct bands or lines.

Shale is actually fine-grained, composed of very small particles such as clay and silt that have been compacted over time. It often has a smooth, layered appearance due to the arrangement of these tiny particles.

No, sedimentary rocks formed from fragments of other rocks are called clastic sedimentary rocks. Chemical sedimentary rocks form from minerals that are dissolved in water and precipitate out to form rocks like limestone or halite.

A sedimentary rock can be reformed by metamorphosis, melting, erosion and relithification, amongst other things. The re-formation would consist of the destruction of the original rock, which would then be reassembled. For example if there is a sandstone, which was then weathered and eroded, then buried and lithified, you would say it had been re-formed.

The crystal size of the minerals that make up sedimentary rock will vary, dependent mostly on the distance the sediments traveled and the amount of weathering they experienced before deposition. The sedimentary rock shale, for instance, is composed of clay and quartz particles which are not visible to the naked eye, and are the product of chemical and mechanical weathering processes over long expanses of time. Quartz sandstone grains, however, are visible to the naked eye, and represent a slightly less rigorous exposure to weathering processes. There are several different methods of sedimentary rock formation which also influence the grain size in sedimentary rocks. Please see the related question below.

Under the category of weather, limestone would be most affected by rain. Rain contains carbonic acid which reacts chemically with the calcium carbonate in limestones. Just try putting a drop of vinegar on a piece of limestone and see what happens. Carbonic acid in rainwater is not nearly this concentrated, though, and the effects take much longer to be noticeable. Tropical climates also produce large amounts of vegetation whose plant roots help break limestone apart, creating more surface area for rainwater to attack. Limestone would be least affected in arid climates, where most erosion is in the form of wind particle abrasion.

Yes, detrital sedimentary rocks have clastic textures. Clastic textures are composed of fragments or grains derived from pre-existing rocks or minerals, which are then compacted and cemented together to form the new rock. Detrital sedimentary rocks, such as sandstone and shale, are formed through the deposition and lithification of these clastic particles.

Shale rocks are composed of fine-grained sedimentary particles, mainly clay minerals such as illite, kaolinite, and chlorite. They are known for their fissility, or tendency to split into thin layers along bedding planes. Shale rocks are commonly found in sedimentary basins and are an important source of natural gas and oil.

Beryl is typically found in igneous and metamorphic rocks, with its formation most commonly associated with pegmatites in igneous rock formations. However, beryl can also be found in some sedimentary environments where it forms as a result of the erosion and re-deposition of beryl-bearing rocks.

Igneous rocks are made from magma. Magma is made of melted rocks. (When it is underground it is called magma, when it erupts on the surface of the earth, it is called lava. It's the same material though.) When magma/lava cools, it forms igneous rocks. There are many types of igneous rocks and the specific type of igneous rock can vary according to which minerals are present in the melted rock, how fast it cools, and the presence of things like water.

Sedimentary rocks are made out of tiny pieces of debris. This can include tiny rocks, sand, clay, silt, and organic material. (Organic materials can vary from rotted leaves to tiny, shelled ocean creatures, or many other types of organic material.) These bits of material collect in an area, then through compaction and cementation, they stick together to form sedimentary rocks.

Sedimentary rocks can also be formed when minerals are dissolved in water and are then resolidified. This type of sedimentary rock is called a chemical sedimentary rock. Oolitic limestone is a good example of this type of sedimentary rock.

Sedimentary rocks are often found as veneer because they are easily weathered and eroded, allowing them to be transported and deposited in various locations. Over time, these sediments can accumulate and form layers, creating a veneer of sedimentary rocks on the Earth's surface.

Yes, North Carolina has various sedimentary rocks such as sandstone, limestone, and shale. These rocks were formed through the deposition and solidification of sediments over time. Sedimentary rocks are common in many regions of North Carolina due to its geological history.

Sedimentary rocks can be formed at any temperature found on the surface of the Earth. Diagensis of sedimentary rocks occurs at temperatures up to the formation of chlorite (200C) from then on they are metamorphic rocks.

Dolostone is technically a sedimentary rock, although it's easy to understand why some might consider it to me metamorphic. In a shallow, tropical sea environment, such as the Caribbean Sea, Calcium Carbonate from shells and fish bones creates a layer of sediment, and since there is no sediment input from things like rivers, the Calcium Carbonate layer does not get mixed in with other types of sediment. Over time, this Calcium Carbonate is compressed into Limestone. Water can easily travel through Limestone, and if that water is rich in Magnesium, the Magnesium in the water will start to replace the Calcium in a process called diagenesis. Magnesium is smaller than Calcium, so empty bubbles called vugs form in the rock. Then new rock, which is made of Magnesium, Calcium, and Carbonate, is called Dolostone. Since the rock never changed due to heat and pressure, dolostone is not metamorphic, and since the rock was not made from lava or magma, it is definitely not igneous.

Yes, sandstone can be banded. Banded sandstone is formed when varying mineral compositions or grain sizes accumulate in layers during the sedimentation process. These layers create distinct bands or stripes in the sandstone rock.

When a sedimentary rock is weathered or eroded, it becomes sediments, or small pieces of rock. Then the sediments are compacted together and they are formed into a new sedimentary rock.

I hope my answer was helpful to you.

Buildings and monuments made of limestone are greatly damaged by acid rain, air pollution, and weathering caused by wind and water erosion. These elements can cause the stone to deteriorate and lose its structural integrity over time.
