How can scientists use a chemical reaction to separate a fossil from limestone without damaging the fossil?
Scientists can use a weak acid solution, such as acetic acid, to dissolve the limestone surrounding the fossil. This process, called acid preparation, helps separate the fossil without damaging it. The acid dissolves the limestone while leaving the fossil intact.
What could take a layer of limestone away from a fossil?
Acidic groundwater or chemical weathering can dissolve or erode away a layer of limestone surrounding a fossil over time. Mechanical abrasion from natural processes like water flow or wind can also wear away the protective layer of limestone, exposing the fossil.
Is limestone made from clastic organis or chemical?
A purely chemical sedimentary limestone would contain no fossil remnants, organic limestone would.
Is true or false limestone can be separated from fossils through the use of vinegar?
In most cases both the limestone AND the fossil will be dissolved by the vinegar (eg a crinoid in Carboniferous limestone), so no. However, some fossils (eg echinoderms in the Chalk) are silicified and in these cases dissolving the limestone in vinegar will expose the fossil in spectacular detail and in other cases the fossil will dissolve more slowly than the matrix, so yes. . In other words there is NO true or false answer, fossil preparation and conservation is a discipline in itself.
Where can you find fossil limestone?
Fossil limestone can typically be found in locations where ancient marine environments once existed, such as near coastlines or in areas with preserved seabeds. Common places to find fossil limestone include quarries, cliffs, and outcrops near bodies of water or former coastlines. It is important to seek proper permits or permissions before collecting any fossils.
Does limestone have cleavage?
Limestone does not have cleavage in the same way minerals like mica or calcite do. Instead, limestone has a crystalline structure that can fracture in various ways depending on the presence of impurities and bedding planes.

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 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 a fossil fuel?
No, limestone is not a fossil fuel. It is a sedimentary rock mainly composed of calcium carbonate. Fossil fuels are formed from the remains of plants and animals that lived millions of years ago, such as coal, oil, and natural gas.

What has the author Nikolaos Solakius written?
Nikolaos Solakius has written: 'Foraminifera and biostratigraphy of the Arnager Limestone, Bornholm, Denmark' -- subject(s): Animals, Fossil, Foraminifera, Fossil, Fossil Animals, Fossil Foraminifera
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 cleavage of a shale rock?
The cleavage of a shale rock refers to its tendency to break along flat, parallel planes due to its layered structure. This cleavage planes are a result of the alignment of clay minerals within the rock, allowing it to split easily along these planes. Cleavage in shale rocks can enhance its ability to split into thin sheets or slabs.
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.
