Igneous rocks contain tiny crystals. Actually, igneous rocks are divided into two types of rocks, which include intrusive igneous rocks and igneous rocks. The name fiery in particular goes back to its Greek origin, the word for fire, meaning to burn or melt.
Igneous rocks contain tiny crystals
Igneous rocks contain tiny crystals The statement is correct because it is formed as a result of rapid cooling or slow cooling, which leads to solidification of the molten material. Igneous rocks are one of three types of rocks known specifically as sedimentary rocks, metamorphic rocks, and igneous rocks.
What are volcanic rocks?
By our topic, plutonic igneous rocks consist of small crystals. In this article we will learn about the types of igneous rocks. In fact, igneous rocks are formed from the solidification of molten rock material. Some of them form below the earth’s surface. while others form above ground. Igneous rocks that penetrate beneath the Earth’s surface crystallize, and the slow cooling that occurs there allows larger crystals to form. Examples of intrusive igneous rocks include diabase, diorite, gabbro, granite, pegmatite, and peridotite. Extrusive igneous rocks also erupt at the surface, where they cool rapidly and form small crystals. Some cool so quickly that they form amorphous glass. These rocks include: andesite, basalt, dacite, obsidian, pumice, rhyolite, scoria and tuff.
Types of igneous rocks
Small crystals are present in the same vein plutonic igneous rocks. Let’s learn about some of the most common types of volcanic rocks. For example, including:
- Basalt: Basalt is an extrusive igneous rock with small crystals, or fine grains as they are called, that are dark in color.
- Information: They are igneous, igneous, igneous rocks that also contain small crystals and are usually pale in color. It contains rhyolite and andesite in its composition.
- Diorite: It is a coarse intrusive igneous rock. It also contains a mixture of feldspar, pyroxene, hornblende and quartz.
- Capro: It is distinguished by its dark color as it contains feldspar, pyroxene and olivine.
- Obsidian: It is a dark volcanic glass that is formed as a result of rapid cooling of molten rock, which leads to the formation of crystals in it.
- Granite: Granite consists of feldspar, quartz and mica. Especially since it is an intrusive igneous rock with coarse grains and light color.
- Peridotite: In fact, it is a stone composed entirely of olivine. These rocks also contain amphibole or feldspar, quartz and pyroxene.
- Pegmatite: It is made of coarse crystals and its color is light. Especially it forms near the magma chamber.
- Rhyolite: These rocks contain quartz and feldspar minerals.
- Pumice: It is a vesicular plutonic igneous rock. Alveolar tissue in particular is formed as a result of molten gas during solidification.
In conclusion, it is clear from this article Igneous rocks contain tiny crystals. These crystals are also called granules. Not to mention that igneous rocks come in different shapes and colors and are formed as a result of slow or rapid cooling.
