Sedimentary rock dating refers to methods used to determine the age of sedimentary rocks and the sediments they contain. This is often achieved through relative dating techniques, such as stratigraphy, which examines the layers of rock and their sequence, as well as through radiometric dating of interbedded volcanic layers or fossils within the sediment. By analyzing the position of rock layers and the types of fossils found, geologists can construct a timeline of geological events. However, direct radiometric dating of sedimentary rocks is challenging due to their composite nature.
What else can I help you with?
Which dating method enables scientists to measure or estimate the absolute age of sedimentary rock?
Radiometric dating of igneous rocks that relate to the sedimentary rock
Radiometric dating is not useful to directly determine the age of rock.?
sedimentary
To date a sedimentary rock layer between two igneous rock units geologists use radiometric dating and assume that the sedimentary layers are?
Geologists use radiometric dating of the igneous rock units above and below the sedimentary layer to establish a time range for the sedimentary rock. They assume that the sedimentary layers are younger than the underlying igneous rock and older than the overlying igneous rock, based on the principle of superposition. This allows them to estimate the age of the sedimentary layer by determining the ages of the surrounding igneous rocks.
What can happen to a sedimentary rock?
It is then sedimentary rock.
Sedimentary rocks can't be dated?
Sedimentary rocks cannot be given an absolute date by radiometric testing, but they can be given an estimated date from a few geological laws, for example if a bed of desert sandstone ins under a bed of limestone there is a law that says that the sandstone is older.
What do Geologists use radiometric dating to date sedimentary rock?
Geologists use radiometric dating of volcanic ash layers within sedimentary rock to determine the age of the sedimentary rock. By dating the igneous rock layers above and below the sedimentary rock, geologists can establish a bracket of time within which the sedimentary rock was deposited.

Why is it difficult to dtermine the absolute age of a sedimentary rock?
In most cases, all we have to date are the clasts in the sedimentary rock. Dating the clasts, however, would yield the age of the source rock from which they were derived rather than the current sedimentary rock.
How fossils can be used to determine the absolute and relative age of a sedimentary rock layer?
Perhaps by carbon dating and by comparing with the evolution and dominance of various organisms in the geological time scale.
Is organic rock a type of sedimentary rock?
ORGANIC SEDIMENTARY ROCK`s : Is a type of sedimentary rock because sedimentary rock has three types of sedimentary rock called clastic , chemical , and organic sedimentary rock so yes ORGANIC SEDIMENTARY ROCK is a type of sedimentary rock..........................................
What kind of rock can sandstones be classified as?
Clastic sedimentary rock.
Why is radioactive dating not used on sedimentary raock?
Sedimentary rock is not original source material, its rock that got ground into sand, settled (usually under water), got buried, and then got heated and squeezed back into a form of rock. Lots of sources.
is mushroom rock a sedimentary rock?
a mushroom rock is not a sedimentary rock.
What can happen to a sedimentary rock?
It is then sedimentary rock.
Where would you typically find younger rocks?
If you are talking about sedimentary rock, and the idea of relative dating, then the younger rock would be on top closer the the surface.
How do you use lava to learn about the ages of sedimentary rock?
It is fairly easy to determine the age of lava or volcanic ash using radiometric dating, but much harder with sedimentary rock. But, if a layer of sedimentary rock is in between two layers of volcanic rock, then we know if had to have formed after the first layer and before the second one. If we know how old the volcanic layers are, then we have a general idea of how old the sedimentary layer is as well.
