Which of the following is not an example of Rocks with Phaneritic texture?

Igneous Rocks

• As igneous rocks form out of magma and lava from the interior of the earth, they are known as primary rocks.
• The igneous rocks are formed when magma cools and solidifies.
• When magma in its upward movement cools and turns into solid form it is called igneous rock.
• The process of cooling and solidification can happen in the earth’s crust or on the surface of the earth.
• Igneous rocks are classified based on texture.
• Phaneritic texture refers to a type of igneous rock texture characterized by large, easily visible crystals that are roughly the same size. This texture indicates that the rock has cooled slowly, allowing sufficient time for the crystals to grow to a visible size. Such rocks are called intrusive igneous rocks or plutonic rocks.
• Sudden cooling (at the surface) results in small and smooth grains.
• Intermediate conditions of cooling would result in intermediate sizes of grains making up igneous rocks.
• Granite ,Diorite ,Gabbro and Peridotite are examples of intrusive rocks.
• Basalt ,Andesite ,Rhyolite ,Obsidian and Pumice are examples of extrusive rocks.
