Which rock has the same composition as granite?
Granite is plutonic and rhyolite is volcanic. They have very similar compositions but one is erupted onto Earth’s surface and the other crystallises at depth. As a result, plutonic rocks are coarse-grained and volcanic rocks are fine-grained.

Which rock has the same composition as granite?
Granite is plutonic and rhyolite is volcanic. They have very similar compositions but one is erupted onto Earth’s surface and the other crystallises at depth. As a result, plutonic rocks are coarse-grained and volcanic rocks are fine-grained.
What is the equivalent of granite?
rhyolite
rhyolite, extrusive igneous rock that is the volcanic equivalent of granite.
What are the top 3 most common compounds in the chemical composition of granite?
The chemical composition of granite is typically 70-77% silica, 11-13% alumina, 3-5% potassium oxide, 3-5% soda, 1% lime, 2-3% total iron, and less than 1% magnesia and titania.
What does granite and rhyolite have in common?
These are: acidic, intermediate, basic and ultramafic. Rhyolite and Granite are the most common types of acidic rock. They have similar compositions. Granite is formed when magma cools down deep inside the earth crust.
Do granite and rhyolite have the same chemical composition?
For example, a felsic intrusive rock is called granite, whereas a felsic extrusive rock is called rhyolite. Granite and rhyolite have the same mineral composition, but their grain size gives each a distinct appearance.
Is basalt and granite the same?
Basalt and granite are similar in the they are both igneous, silicate rocks and common on Earth. They also have numerous differences. Basalt is extrusive, mafic, and common throughout the Solar System whereas granite is intrusive, felsic, and common only on Earth.
What is composition of granite?
Granite is the typical type of plutonic rocks, it consists of feldspar, quartz, a few dark—colored mineral, sand, mica. The main chemical propositions of the granite are SiO2 (65% ~ 70%), a little of Al2O3,CaO,MgO and Fe2O3, thus the granite is acid rock.
What is granite stone made of?
Granite (/ˈɡrænət/) is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground.
How does obsidian and granite differ?
Obsidian is not a genuine mineral or “rock.” It is a natural glass that contains microscopic mineral crystals. Granite, the most common rock on the continental crust, is composed of visible crystals of feldspar, mica, quartz and other minerals.
What type of material is granite?
intrusive igneous rock
Granite (/ˈɡrænət/) is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground.
Why is granite more common than rhyolite?
Why is granite more common than rhyolite? Mafic magma is much hotter than felsic magma. Because of this, it is easier for the basaltic lavas to reach the surface while still in the liquid phase. … Therefore, more basalt than gabbro, and more granite than rhyolite.
How are granite and diorite similar?
Like other igneous rocks, granite and diorite formed from crystallized molten material, and both are extremely hard and sport a mottled pattern. They are also somewhat porous and need a finish when used in a wet location.
