What is the texture of Intrusive igneous rocks?
An igneous rock has two different textures. Extrusive rocks generally are smooth and glassy. Intrusive rocks are generally coarse
What is a rock with two different textures called?
Porphryitic igneous rock is composed of phenocrysts embedded in a finer matrix.
Which two igneous rocks have phaneritic textures?
Even in the most generalized classification, more than two igneous rocks have phaneritic textures. In that generalized classification, they are granite, diorite, gabbro, and peridotite.
What are 2 textures of metamorphic rock?
The two textures of metamorphic rocks are the Foliate and Non-foliate textures.
What type of igneous rocks are there?
Two types: Extrusive igneous rock and Intrusive igneous rock.
Why can two igneous rocks have the same minerals but different names?
The rocks may have different textures

How do two igneous rocks have the same mineral composition but different textures?
The texture of an igneous rock refers to the size of its mineral crystals. If the common magma of both igneous rocks has experienced differences in cooling rates due to depth, they will have different textures. Slow cooling produces large crystals, and quick cooling produces small crystals. Granite and rhyolite are two igneous rocks sharing the same mineral composition, but having undergone different rates of magma cooling due to depth at solidification.
Which two igneous rocks have phaneritic textures?
Even in the most generalized classification, more than two igneous rocks have phaneritic textures. In that generalized classification, they are granite, diorite, gabbro, and peridotite.
Why is igneous rock called a mother rock?
Igneous rock is a category of rocks a parent rock can be igneous metamorphic or sedimentary
What are 2 textures of metamorphic rock?
The two textures of metamorphic rocks are the Foliate and Non-foliate textures.
What does extrusive rock means?
Extrusive igneous rock is one of two different types of igneous rocks. The other kind is intrusive igneous rock. Intrusive igneous rock is formed when magma in Earth's lithosphere cools and hardens. Extrusive igneous rock is formed when lava on Earth's surface cools and hardens.
What type of igneous rocks are there?
Two types: Extrusive igneous rock and Intrusive igneous rock.
Why can two igneous rocks have two same minerals but different names?
Although chemically equivalent, they would be different in their method of formation. Granite is an intrusive igneous rock, cooled from magma under the surface. The rock rhyolite is the chemical equivalent of granite, but formed on the surface, making it an extrusive igneous rock. Intrusive rocks have larger crystals.
Which rocks has two different size grains of the same mineral?
The rock is conglomerate. The other rock would be Breccia if its grains were not rounded.
A lava flow is an example of an igneous rock one of the two main igneous rock groups?
It is an example of extrusive igneous rock.
