mineral veins.. I think it may be rock fragments as well though depending one what kind of rock.. Mineral veins will work with metamorphic and igneous rock. It may also work for sedimentary rocks.. I had the same question btw

Is an extrusion older or younger than the rock layer below it?
Extrusion is older than intrusion because, an extrusion is always younger than the rocks below it. An intrusion is always younger than the rock layers around and beneath it. Hope the answers correct ;)
How is the law of superposition is used to date fossils?
Superposition is the methodology of younger sediments being deposited over older rocks. Paleontologists can determine the evolution or extinction of a species by looking at what fossils are either present or absent in a particular sedimentary layer.
What does the principle of superposition tell you about the relative ages of sedimentary rock layers?
Younger layers are deposited on top of older layers, whether the layer is sedimentary or volcanic. Occasionally faults may result in overthrusts, where a series of older layers may be pushed over the top of younger layers. But this is rare. In general, the older layers will be the lower layers.
A relative age of the rocks of the earth's crust can be determined by using the laws of what?
There are three laws of science that scientists use to date the crust by studying the layers of rocks. These laws are called the Law of Original Horizontality, the Law of Superposition, and the Law of Faunal Succession.
How old can a jaguar get?
older than 20 years old.
How is it that crosscuting feature is always younger than the rock layer it cuts across?
A crosscutting feature is always younger than the rock layers it cuts through because the feature always forms after the rock layers have been formed, making the rock layers older.
A fossil found under a layer of rock is usually?
older than the rock!
What is a fossil found under a layer of rock is usually?
It is usually older than the rock layer it is found under.
What is A fossil found under a layer of rock is usually .?
It is usually older than the rock layer it is found under.
Is the fault older or younger than rock layer A?
older because it is at the bottom and the ones on top are younger than the bottoms
How is it that crosscutting feature is always younger than the rock layers in cuts across?
A crosscutting feature is always younger than the rock layers it cuts through because the feature always forms after the rock layers have been formed, making the rock layers older.
Do you find older rock above or below younger rock?
The law of superposition states: in horizontal rock layers, each layer is older than the one above it and younger than the one below it.
Is a fossil older or younger than a another fossil in a lower rock?
According to the geologic Law of Superposition, in undisturbed rock strata, the deepest rock layers are always the oldest. Accordingly, a fossil found in a lower layer of undisturbed rock would be the older.
In general the law of superposition states that in an undeformed sequence of sedimentary rock each layer is?
Younger than the layer below it.
What statements states relative age?
"The fossils found in this rock layer are older than the fossils found in the layer above it." "The granite intrusion is younger than the surrounding sedimentary rocks." "The volcanic ash layer is slightly older than the layer of soil above it." "The erosion pattern on the hillside indicates that the granite rocks are older than the layers of sediment deposited on top of them." "The cross-cutting relationship between the fault and the layers of rock indicate that the fault is younger than the rock layers it cuts through."
If in the Grand Canyon walls if a fossil imprint of a leaf is lower than a shell fossil does that mean that the leaf fossil is older than the shell fossil?
The strata or rock layers of the grand canyon walls are undisturbed. As such, a layer of rock containing a fossil, that is below an overlying rock layer will be older.
Is the age of the Earth older than any surface rock layer?
Yes, the planet Earth is older then any rock layer found on its surface. When Earth first formed it was entirely molten and layers of rock did not start forming until after it had cooed and the surface had solidified.
