What is an igneous intrusion between two sedimentary rock layers?
A laccolith is an igneous formation between two sedimentary layers
Consisting of layers of different minerals?
igneous rocks
How do you classify igneous rocks from other types of rock?
Igneous rocks are identified by first looking at the color index. Felsic igneous rocks contain mostly potassium feldspar. Intermediate igneous rocks contain mostly plagioclase feldspar. Mafic igneous rocks contain pyroxene, olivine, and plagioclase feldspar. Ultra mafic igneous rocks contain mostly olivine. Then igneous rocks are identified based on texture. For example, the texture of igneous rocks can be aphanitic, pegmatitic, phaneritic, glassy, vesicular, etc.
What type of rock layer does mount st helens have?
As Mount St. Helens is a volcano the slopes would be covered in layers of volcanic dust and lava.
Can sedimentary rock be changed into igneous rock?
If it is forced back into the molten layers of the Earth, then yes, it will become igneous rock.

Does igneous rock have visible layers?
no
What is the type of rocks which contain fossil fuels?
I think they're found in the fossils of dead animals or plants.
Consisting of layers of different minerals?
igneous rocks
Does an igneous rock contain iron?
Most igneous rocks would likely contain a varying amount of iron.
Which igneous feature is formed when magma is forced into layers parallel to the surrounding rock layers?
A sill.
What kind of rocks do not have layers?
Igneous rocks, non-foliated metamorphic rocks, and evaporites do not have layers.
When layers of sediments are pressed together form.?
Igneous rock
Are igneous rocks formed by pressing layers of rocks together?
No. Igneous rock is formed from cooling lava or magma.
Which rock layer can you date by radioactive dating using half- life?
Rock layers of igneous and some metamorphic rock that contain certain radioactive isotopes are datable by isotopic techniques.
Sheets of igneous rock that are parallel to the layers they intrude?
A sheet of igneous rock that protrudes into the surrounding layers of rock is called a dike. Dikes are most often horizontal sheets that can form in many layers.
