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.

∙ 13y agobecause most creatures like the taste of lime so they found rocks that tasted like lime and they normally died near those rocks.

In which type of sendimentary rock will you find embedded seashells?
Limestone.
In which type of rock would you mostly likely find fossil?
Sedimentary.
Is limestone dissolved by carbonic acid chemical or mechanical?
The dissolution of limestone by rainwater containing carbonic acid is the perfect example of chemical weathering.
How sandstone shale and limestone form?
Limestones are form by precipitation of rusually under water Sandstones are formed from sendiments that are being eroded and compacted and cemented together. Shale are formed from precipation also but you often see fossil records on them.
What rock results from the metamorphism of limestone?
Marble is one form of metamorphosed limestone.
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.
How are inclusions used in the relative dating process?
The Law of Inclusions basically states that any rock (or mineral or fossil) that is entirely within another rock must be older than the rock containing it. The rock containing the inclusion formed around the already existing rock, thus preserving it inside. For example, a fossil bone found in limestone is necessarily older than the limestone surrounding it.
In which type of sendimentary rock will you find embedded seashells?
Limestone.
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 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 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 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
How are coal and limestone different?
LImestone and coal are different because of their outcomes. Limestone , after the cementing, becomes a rock. Coal, after the pressing together, becomes a fossil.
What are some examples of calcite containing rocks?
limestone marble
What is the name of the stone containing calcium carbonate that is quarried?
limestone
