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.
The igneous rock texture characterized by two distinctly different crystal sizes is the texture?
Porphyritic
A laccolith is an example of a(n) igneous rock (one of the two main igneous rock groups).?
intrusive
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.
What is a rock with two different textures called?
Porphryitic igneous rock is composed of phenocrysts embedded in a finer matrix.
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.
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.
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.
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.
The igneous rock texture characterized by two distinctly different crystal sizes is the texture?
Porphyritic
Which rocks has two different size grains of the same mineral?
Pegmatite is a type of igneous rock that can have two different grain sizes of the same mineral present. This is due to the slow cooling process of the magma, allowing for the growth of large crystals (phenocrysts) within a finer-grained matrix.
What is basalt sedimentary ignous or metamorphic?
actually, it truly depends on the type of rock the metamorphic rock formed from. in other words, if it formed from a rock that held basalt in it, the rock has basalt in it. remember that a metamorphic rock can be formed by more than two different types of rock (such as metamorphic quartz, slate, "fool's gold", plus granite). it does not matter which class the metamorphic rock formed from (but if a m. rock such as m. quartz, there is more likely a chance of finding a trace of basalt), as long as it formed from two different class of rock (this does not always apply, for there can be a metamorphic rock made from two or more metamorphic rocks). i would get into geodes...... but that's another answer. :)
