Fossiliferous (yes, that is a word) limestone forms from organism rich sediments or coral reefs in usually shallow marine environments. Shells of small marine organisms are most often formed of calcium carbonate. In time, the weight of the accumulated shells and sediments cause a gradual sinking of the material. With additional sediments constantly accumulating, the weight from above causes compaction of those sediments, squeezing out air and fluids from the space between the shells and shell fragments. These particles are cemented together by the mineral calcite which precipitates out of the remaining fluids. The compaction and cementation are part of the process of lithification, or rock formation.
What else can I help you with?
Is limestone dissolved by carbonic acid chemical or mechanical?
The dissolution of limestone by carbonic acid is a chemical process. Carbonic acid reacts with the calcium carbonate in limestone to form calcium bicarbonate, which is soluble in water. This chemical reaction causes the limestone to dissolve.
What chemical limestone form?
Limestone is primarily composed of the mineral calcite, which is a crystalline form of calcium carbonate (CaCO3). This chemical forms through the precipitation of calcium-containing ions in water, or can be produced by the accumulation of marine organisms such as corals and mollusks over time.
How do you form Carbon Dioxide?
Carbon dioxide is formed when carbon-containing compounds, such as fossil fuels or organic matter, are burned in the presence of oxygen. During combustion, carbon (C) combines with oxygen (O2) to form carbon dioxide (CO2) as a product.
In which type of sendimentary rock will you find embedded seashells?
You are likely to find embedded seashells in limestone, which is a type of sedimentary rock formed from the accumulation of coral, shells, and other organic material.
What rock results from the metamorphism of limestone?
Marble is the rock that results from the metamorphism of limestone. Through the process of heat and pressure, the calcium carbonate in limestone recrystallizes to form marble with a characteristic crystalline structure and unique patterns.
How can scientists use a chemical reaction to separate a fossil from limestone without damaging the fossil?
The limestone containing a fossil would be heaated to a sufficiently high temperature (about 1,800 centigrade).then the limestone would become powder and the fossil which is not as sensitive to heat as limestone would remain un damaged
Is limestone a fossil fuel?
Limestone is not a fossil fuel because it is not made from the carbon-containing soft tissues of long dead plants and animals. It is formed by fossils based on animal shells. Limestone is not used as a fuel but is used by industries for other purposes.
Why are buildings made from limestone affected by the products from burning fossil fuels which contain sulfur?
Buildings made from limestone are affected by sulfur compounds from burning fossil fuels because sulfur dioxide in the air reacts with limestone to form sulfuric acid. This acid causes the limestone to deteriorate by dissolving and weakening its structure through a process known as acid rain.
What is the difference between fossil rich limestone and chemical limestone?
fossil rich limestone is made by the earth and is enhance with fossils although the chemical is man made, the two are basically the same.
What is permeable rocks containing water?
limestone
In geography what are stalagmites?
In areas where the rocks are made of limestone, water will dissolve the limestone and form underground caves. In these caves water containing dissolved limestone will drip from the roof. As the drips form some of the water evaporates and limestone is deposited out of solution. Thus, from where the drips are occurring and on the floor below, pilers start to form, the pilers on the floor are called 'stalagmites' and the pilers hanging from the roof are called 'stalactites'.
What could take a layer of limestone away from a fossil?
If the fossil is replaced with silica the easiest way to remove the limestone is with weak acid such as vinegar. If the fossil is also limestone the best way to free it is by carefully removing the limestone with small picks and drills. This is usually best left to expert conservators as it can be delicate work.
What is fossil rich limestone?
Fossil rich limestone is limestone with various sea creature fossils in it such as shells. It is organic and fine grained. It is sedimentary... Yea that's it :P
Is limestone dissolved by carbonic acid chemical or mechanical?
The dissolution of limestone by carbonic acid is a chemical process. Carbonic acid reacts with the calcium carbonate in limestone to form calcium bicarbonate, which is soluble in water. This chemical reaction causes the limestone to dissolve.
What is the name of the stone containing calcium carbonate that is quarried?
limestone
What are some examples of calcite containing rocks?
limestone marble
What chemical limestone form?
