When magma cools, it forms igneous rock.
Epidote is formed from a set of minerals, and it is used to form other mineral types of its own kind by chemical reactions on it.
Extrusive igneous rocks. The type of extrusive igneous rock is determined by the composition of the lava.
When all minerals form a special kind of solid, it is called a "mineral aggregate." This term refers to a collection of minerals that are physically combined but retain their distinct properties. In geology, these aggregates can also form rocks, where different minerals crystallize together under specific conditions.

Igneous rocks are formed from the cooling and solidifying of magma. The resulting rock can be instrusive (magma cooling within the crust) and extrusive (lava cooling on the surface). The most common kind of rocks are Granite (intrusive) and Basalt (extrusive).
Igneous rock, such as granite or diorite, is formed from magma that cools below the Earth's surface. It has a coarse-grained texture due to the slow cooling process, allowing large mineral crystals to form.
Igneous rock forms when magma cools and hardens. This type of rock can be classified as intrusive (plutonic) if it cools below the Earth's surface (slow cooling) or extrusive (volcanic) if it cools quickly on the Earth's surface. Examples of igneous rocks include granite, basalt, and obsidian.
Igneous rocks form from magma as it cools and solidifies. Examples include granite, basalt, and obsidian.
Aphanitic, or fine-grained.
Magma beneath the surface typically cools slowly, allowing for the formation of large crystals. This slow cooling process is known as intrusive or plutonic cooling. In contrast, lava that reaches the surface cools much more quickly due to exposure to lower temperatures and can form smaller crystals or glassy textures.
Igneous rock is formed.
When molten rock cools slowly, it will have a lot of time to form crystals, so the crystal size will be quite big. Take granite, for example. With the naked eye, you can see the individual crystals. The grain size is quite large. The kind of mineral that forms is dependent on the composition of the magma.
If the magma cools on the surface of the crust, it is called extrusive igneous rock, such as pumice, basalt or rhyolite. If the magma cools inside the crust, it is called intrusive igneous rock, such as granite.
Intrusive igneous rock.
Intrusive Igneous Rock.
It depends on the composition of the magma, how quickly it cools and crystalises, the temperature and pressure of the original melt.
Extrusive igneous rocks such as basalt or rhyolite.
