Dikes: Tabular, discordant intrusive igneous bodies that cut across existing rock layers. Sills: Tabular, concordant intrusive igneous bodies that form parallel to existing rock layers. Laccoliths: Intrusive igneous bodies that are lens-shaped and have uplifted the overlying rock layers. Batholiths: Large intrusive igneous bodies that cover at least 100 square kilometers. Stocks: Small intrusive igneous bodies that are less than 100 square kilometers in size.
These small intrusions are likely dikes, which are vertical or near-vertical sheet-like bodies of intrusive igneous rock that cut across the existing rock layers. They are formed when magma is injected into existing fractures and solidifies underground. Dikes can provide insight into the geological history of an area and the direction of magma flow.
Igneous rocks can be either extrusive or intrusive. Extrusive igneous rocks form from lava cooling quickly on or near the Earth's surface, resulting in small crystals. Intrusive igneous rocks form from magma cooling slowly beneath the Earth's surface, resulting in larger crystals.
Syenite - Wikipedia, the free encyclopediaSyenite is a coarse-grained intrusive igneous rockof the same general composition as granite but with the quartz either absent or present in relatively small amounts (
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.

Intrusive rock normally has visible crystals. Extrusive igneous rock has small crystals. A black extrusive igneous rock with small crystals could be basalt.
by the size of the crystals, big crystals intrusive, small crystals extrusive
That is correct.
Two Small Bodies was created in 1993.
The duration of Two Small Bodies is 1.47 hours.

Small icy bodies are located in the solar system where they orbit the sun.
There are various small bodies in the solar system .These include moon, asteroids, rocks etc.
