What else can I help you with?
What type of rock are you most likely to find a fossil?
You are most likely to find them in sedimentary rock.
Does limestone turn water blue?
No, limestone is a sedimentary rock that is the basis for marble if it is compressed by millions of years of pressure. Limestone consists of calcium carbonate, CaCO3. Limestone dissolved in slightly acidic water forms the basis of stalactites and stalagmites in limestone caves.
What is a dark sedimentary rock formed by compression of layers of clay-rich sediment?
Shale is made from layers of mud and clay pressed together. :)
What is a true fossil?
A True form fossil is a fossil of the whole/entire body of the organism.
What kind of fossil leaves a body impression?
This is called a trace fossil. or a mold.
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 sedimentary rock in which the older rocksunless disruptedare on the bottom?
The type of sedimentary rock in which the older rocks, unless disrupted, are on the bottom is called a fossil-rich limestone. This rock contains fossil remains of prehistoric organisms.
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
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.
Which period did the redwall limestone form?
The Redwall Limestone formed during the Mississippian period, which is part of the Carboniferous era. This period lasted from about 359 to 323 million years ago. The limestone is primarily found in the Grand Canyon region and is known for its rich fossil content, including marine organisms that thrived in shallow seas at the time.
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.
Which part of the Midwest has rich fossil beds?
The Midwest region of the United States, particularly in states like Iowa, Illinois, and Kansas, is known for having rich fossil beds. These areas were once covered by ancient seas, which preserved a wide variety of marine fossils that can be found in limestone deposits and shale formations.
Is limestone made from clastic organis or chemical?
A purely chemical sedimentary limestone would contain no fossil remnants, organic limestone would.
What colourcan iron rich limestone be?
yellow
What type of rock is calvert cliffs?
Calvert Cliffs consist of sedimentary rocks, primarily sands, clays, and fossil-rich limestone. These rocks were deposited over millions of years during the Miocene epoch.
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.
What is the cleavage of fossil limestone?
Fossil limestone typically does not exhibit cleavage in the same way that some other sedimentary rocks do. Instead, it tends to break along natural fissures or bedding planes due to its composition of calcite or aragonite minerals. The presence of fossils can also influence how it fractures, often resulting in uneven surfaces. Overall, fossil limestone is more characterized by its grainy texture and fossil content than by distinct cleavage planes.
