An intrusive igneous body that is not characterized as such is a volcanic ash layer. While intrusive igneous bodies, like batholiths, sills, and dikes, form from magma that cools and solidifies beneath the Earth's surface, volcanic ash layers are formed from explosive volcanic eruptions and are deposited on the surface. Therefore, volcanic ash layers do not qualify as intrusive igneous bodies.

What one of the following is not a intrusive igneous body?
An intrusive igneous body is formed from magma that cools and solidifies beneath the Earth's surface. Common examples include plutons, batholiths, and sills. However, a volcanic eruption, which involves the extrusion of lava onto the surface, is not an intrusive igneous body.
A laccolith is an example of a(n) igneous rock (one of the two main igneous rock groups).?

A type of intrusive igneous rock with larg crystals?
Basically, all intrusive igneous rocks have large crystals. Because they are intrusive, they take a long time to cool down, and so there is a lot of time for crystal growth. That said, the biggest categories of intrusive igneous rocks are: Peridotite (ultramafic) Gabbro (mafic) Diorite (Intermediate) Granite (silicic/felsic) Granite is the most common one in the continental crust.
What is igneous rock?
Igneous rock is one of the three main rock types based on the method of its formation. It is also referred to as plutonic or volcanic rock depending on where it formed. In a nutshell, to be classified as igneous, a rock must have crystallized and solidified from molten rock (magma) either below ground (intrusive igneous rock) or at or near the surface (extrusive igneous rock).
What are facts about igneous?
.The oldest rock known today is the Igneous rock. .Igneous rock can be any colour..The word "Igneous" is a Greek word that means fire. Igneous rocks are formed by the cooling of molten rock, lava or magma. When magma solidifies in the earth they are intrusive, when lava cools outside the earth it is extrusive.

Which one has large grains between intrusive and extrusive igneous rocks?
intrusive
What is an intrusive igneous rock made from magma?
Granite is one example.
What does extrusive rock means?
Extrusive igneous rock is one of two different types of igneous rocks. The other kind is intrusive igneous rock. Intrusive igneous rock is formed when magma in Earth's lithosphere cools and hardens. Extrusive igneous rock is formed when lava on Earth's surface cools and hardens.
Why is intrusive rock an extrusive rock?
It is not. An igneous rock is either one or the other.
What is the type of Igneous rock that forms underground?
Igneous, Metamorphic, and Sedimentary rocks

Do you think extrusive or intrusive igneous rocks are likely to have larger crystals?
If a rock has large crystals, it is an intrusive rock. Intrusive rocks form underneath the Earth's surface. Magma cools slowly so it has time to form large crystals. An example is granite, where you can see the crystals with your naked eye. Rocks that have small crystals are extrusive rocks. Extrusive rocks are ones that form from lava (blasted out of a volcano) so they cool very quickly, not allowing large crystals to form. An example is obsidian, where you cannot visibly see the small crystals; it just looks like one black, glassy rock.

What are quartz occurrences?
Smoky quartz is usually found in intrusive igneous and certain high grade metamorphic rocks, like granite and orthogneiss. Orthogneiss designates a gneiss derived from an igneous rock, and prognosis is one from a sedimentary rock.
