Sometimes. The sediments themselves cannot be dated by radiometric methods, because the radiometric dates will reflect the original formation of the rocks from which the sediments were derived. But the sedimentary rocks may contain datable material, such a fossils of a characteristic form, or there may be a datable layer of volcanic material above or between sedimentary layers. Also, it is sometimes possible to determine the age of rocks by comparing the alignment of magnetic mineral grains within them with the history of magnetic pole reversals.
What else can I help you with?
What can you find within layers of sedimentary rock?
As sedimentary rock is deposited at over time, you can find fossils in it.
What do you call the layers in sedimentary rock?
Sedimentary rock layers. your welcome
What evidence would a scientists use to determine the absolute age of a fossil found in sedimentary rock?
The Igneous intrusions and extrusions near sedimentary layers.
What rocks is formed in layers?
Sedimentary rock, like limestone, is formed in layers.
What rock formed in layers?
sedimentary rock
In what type of rock would you most likely find layers?
Sedimentary rock, most likely.
What type of rock forms in layers?
That would be sedimentary rock, and (honorable mention) occasionally metamorphic rock.
Can geologists use radioactivity to find the absolute ages of sedimentary layers?
No, if you use radiometric dating techniques on sedimentary rocks you will find the age of formation of the constituent grains which will originally have been weathered and eroded from a source or parent rock and as such the age of the grains is potentially much larger than the age of the sedimentary rock that they have since been deposited to form.
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.
How can igneous rock disturb sedimentary rock layers?
Igneous rocks can disturb sedimentary rock layers and formations by their movement during ascent through such layer. when they make contact with this sedimentary rocks they could result to folding and/or metamorphism.
In which type of rock would you mostly likely find fossil?
You would most likely find fossils in sedimentary rock. Sedimentary rocks are formed from layers of sediment that accumulate over time, which can help preserve fossils in the rock.
What is layers of rock called?
sedimentary
