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 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 rocks is formed in layers?
Sedimentary rock, like limestone, is formed in layers.
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 rock formed in layers?
sedimentary rock
What is the process by which layers of sedimentary rock are formed?
The process by which layers of sedimentary rock are formed is called strata.
What is a rock made of layers that are cemented together?
Layers of sediment which have undergone lithification are called 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.
Archaeologists tend to find fossils most often embedded in which type of rock?
Sedimentary rock layers
Where can strata can be found sedimentary rock or igneous rock?
Sedimentary Rock. Strata is layers of sedimentary rock that form from the deposition of sediment.
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.
